It looks like we have an
official answer from WotC:
"Do you intend to post any rules updates or corrections for D&D Gamma World, like you do for 4E? While built on the same system, Gamma World and D&D 4E are two very different beasts with different focuses when it comes to feel and balance. The first (stickied) thread in the Gamma World forum contains questions and answers generated by the community, links of interest, and a lot of other helpful info for Gamma World players and GMs. Right now, our errata reviewers are focused on getting D&D books and online articles up to date. When they get caught up on that process, they'll look at the Gamma World forum and determine whether anything in it needs to be addressed officially. For now, that thread is a terrific resource (and we appreciate all the work that dedicated fans have put into it)."
If they had not spent time gathering information about rules issues, I could understand them not releasing errata. However, considering that they spent time to gether info, I am annoyed that they are just letting it sit idle.
I have not seen anything saying they had spend a lot of time on that. Indeed, thier statement seems to indicate that if they do decide to gather information, it will primarily be from the forum FAQ... and that for now, the forum FAQ is your best resource.
So if want a particular clarification or correction... it's just a matter of speaking up here. Not sure how to make it easier than that.
fwiw: there are actually a lot less rules issues than I would've expected for this product (i.e. it was created on a tiny budget), and it got an honorable mention in the Ennie Awards Best Rules category.
