Avengers movie line-up?

Over at i09, this poster made a movie poster depicting what we already know about the upcoming Avengers movie. Could this be our Avengers line-up?

Here is the link.

And here is the picture:
There are also rumors of casting Jeremy Renner as Hawkeye, but if the comments of the rumored actor are true, I want no part of the Ultimate Hawkeye. I demand purple tights and a bow and arrow!!!

Here are links to the concept art for Captain America's movie costume and Thor's full costume. I hope they are planning a little more variety on Thor from the waist down, and a winged helmet. PLEASE let there be a winged helmet!
