A Quick update on my post from yesterday:

Madhouse is currently in production on the first of four new series (12 x 30 minutes), which are scheduled to launch in spring 2010. The initial series will feature characters including Iron Man and Wolverine, among others, and Madhouse will ultimately look to adapt the entire Marvel Universe, creating in essence a whole new character base for Marvel (Anime News Network)

So we now know that these are actual series, 12 episodes 30 minutes each and that Iron Man and Wolverine are 2 of the 4 in production.  I hope Doc Strange is in the mix.  I can only imagine that Anime glory that would be.
