According to Wikipedia, Marvel has no animated films set for release until 2011 which is 'Thor, Tales of Asgard'.
They do seem to be investing in animated series though:
The Avengers: Earth's Mightiest Heroes ------ Oct. 2010 on Disney XD
Thor --------------------------------------- Fall 2010/TBA
Marvel Anime ------------------------------- 2011 on G4
Ultimate Spider-man ------------------------ Fall 2011 on Disney XD
Again this is according to Wikipedia, so.................who knows.
There was also a Black Panther animated series but it was for ABC3, an Australian network, and only shown overseas.
I agree that Marvel needs to step up their animation output. Their focus seems to be live-action right now. But they could do both. And I think the animated features will show truer portrayals of the characters anyway. Don't get me wrong, I like live-action stuff. But animated features have a better tone and quality to me and lend to the escapism so much better.
