I have done a ton of research on that subject.  I have posted every single relevent detail on these forums.  I don't understand why you cannot find it.  Oh... that is right.  I remember why you cannot find results on any of my extreamely meticulous research.  It is because there is zero information.  There are zero hints.   We have no idea if there will be any other new Dungeon Command editions.   And we certainly have no idea what those editions might be.  When the creators of this game talk about what will be released after Blood of Gruumsh, they simply say that they are not authorized to tell us anything about future faction packs.  

I would bet that Dungeon Command is profitable and more will be released soon and that the next one will fit into the pattern of the last five.  Themes have been:  mixed racial group of adventurers, band of drow, goblinoids, scary undead, and orcs.  Dragonborn, fey, kobalds, elves, humans, demons, angels, lizardfolk or abborrations all seem like likely possibilities. I don't know enough about forgotten realms to make a great guess.  Wide marketability is probably the key to how the creators choose future faction packs.

The only way that we are going to get more dungeon command faction packs is if the game is profitable.   If you want to see more faction packs, the only thing you can do to make that a reality is to buy more faction packs.  The four faction packs already out are all great.  To be painfully honest though, if the series is going to end with the Blood of Gruumsh, I will be sad that there will never be more than about 8 different types of wisdom cards (admittedly, I don't know how many wisdom cards will come in the last set).

I suppose I am just optomistic because of who I am.  My optomism is certainly not based on a wealth of data.  And I certainly don't have any experience analyzing the profitability of other boards games.  The only reason I have done so much research on this game is because I enjoy this product so much.  But I have noticed that few people buy this game besides me.  I have bought six copies (two for a friend) and four months ago I met someone else who bought three copies.  Otherwise, I haven't had any nonvirtual contact with anyone who has bought this product.

 While I am forced to admit that the current lack of information isn't promising, that doesn't mean we have to count the game out yet. Blood of Grummsh is still more than two months away. Following the same time line release means that any future faction packs wouldn't even see release until May.
 That's far enough out that there's still reason to be hopeful that the game will be successful enough to warrent a continuation of the series.  If Grummsh is released and we still have nothing about the next faction pack .... well then, that's probably going to be the end. I'll continue to be optomistic until then.
 In the meantime, get out and try to get your local hobby shops setting up tournaments!  

 I dunno, Wisdom is pretty underrepresented. You've only got couple Creatures that use it currently, and an even fewer number of cards. Grummsh would have to be a major Wisdom set to really give us a "complete" game. 
 And if you're using the Order Card make up to define a complete set, you'd also need to to take into accounte the creatures that use them. Intelligence has a fair number of cards, but only high level Creatures that can use them. We need some low level Int. Creatures to help fill out the Intelligence set a little better.
 If Wizards of the Coast is going to go for a full set before letting us loose, they're really going to have to give us about 3-4 more faction boxes AFTER Blood of Grummsh.  

 I'm not saying that they won't cut us loose, just that if that's their line of reasoning then would need to give us more than the initial five faction sets we currently know about.  

I only recently got my first three sets of the games (Lolth, Undeath, and Goblins) and I find the game astounding. Just within these three boxes is such an intriguing and deep game. Add in the option for Warband and Order Deck customization, and we could have Wizard's next MtG. The metagame for this could be so deep and create an extremely interesting tournament or sanctioned play environment. Removing the random aspect of the release (which many companies have been doing in ever expandable games) should hopefully help in it sales. Especially for those collecting miniatures for RPGs and such.

Now in regards into creating a successful, lasting game, I'm not sure how we can truly gauge it without sales numbers. I'd hope they were high. I think the reason Wizard's biggest licenses (Magic and D&D) are due to their history. D&D has been around for so long and pulled in so many players and fans that it will always sell. Until Wizards does something incredibly drastic to it (which 4th Edition almost seemed to some), its sales will not die. Magic also has an incredibly developed history and metagame, with a ton of options for game play and card variety. Regardless of whether the game play itself is of the highest quality or not, it continues to sell quite a bit. As we've seen quite a few times with Magic though, they've attempted to tag the license onto other products but they have relatively failed (with the odd exception of Duel of the Planeswalkers, which is just the card game itself watered down by removing the true depth of MtG). Luckily, this has not been the same with D&D. Their released board games are quite popular (my LGS group plays a couple of them often) and the material itself has inspired quite a bit of other fantasy material. And we all know hard core role players want good quality miniatures for their gaming. Hopefully Dungeon Command can fill that as well as provide a great game.
