I found the 1st episode of Anime Iron Man and 4 others! Episode 4 is, at this point, still missing. Trying to locate it now, but until then all of these episodes are available to watch online, with English Subs.
http://www.megavideo.com/?d=G1W4HDZL - Episode 1 "Iron Man Arrives in Japan."
http://www.megavideo.com/?d=EN78LONG - Episode 2 "Going Nuclear."
http://www.megavideo.com/?d=QPBM8SKT - Episode 3 "The Revival Project."
http://www.megaupload.com/?d=MWAUSG2M - Episode 5 "The Arc Station Infection."
http://www.megavideo.com/?d=TBB56K9O - Episode 6 "Technical Difficulties."
A little something to help ease the pain while we wait on more "Avengers" footage and pictures.
