2 years ago when i susbribed Because of These prototype materials for dnd insider, " those applications than DnD insider as subscriber was HOPEING for access to these tools. "
Of course tha isn't a Commited Ralationship. It's more a Transaction, I give you my money for some Product will be release soon.
I'm sorry, that's not how it works. You give them some money and they give you the product they have now. WotC has not now, nor have they ever, requested anyone give them some money in return for "some product that will be released soon". DDI has always been a subscription to their existing content.
Now, you can be disappointed it hasn't expanded to more tools, you can be frustrated by them advertising/hoping for upcoming products on which they failed to deliver - but you cannot hold them accountable for having made a transaction for non-existent tools, because that never happened other than in your own mind.
If you want the promised tools? If that is all you care about? Then wait until they are released and subscribe then.
Buying a subscription now out of the hope for upcoming products is your own choice, and not one that WotC has any responsibility for. Either they are offering you a product you find worthwhile, right at the moment you pay for it, or they aren't. Making decisions based on anything else is meaningless, and it's on you if you choose to do so.
I can't emphasize this enough. If you find the product worthwhile, pay for it. If you don't, leave it be. If you think a new upcoming tool will make the difference, wait for that tool, and make your decision then.
