I'm pretty sure that Bethesda was already mostly finished with Skyrim when they announced it...i think now they are just working on sounds and fixing any problems, so don't expect them to be reading these ideas from this forum and putting them into the game. Even if they aren't nearly finished, i highly doubt they will come on this forum to get game ideas.
Maybe not,but there is still DLC .
I don't know a great deal about game development,but doesn't 9-10 months sound like a lot of time to be fixing bugs/polishing etc?
Surely the can still add stuff....they even said in an interview they have far better tools now,to put things in game quicker from concept to the actual game.
Like i said i don't know a great deal.
