UPDATED IMPRESSIONS:
I only skimmed the Newarama article the first time. Went back to look at the art, here's what I got out of it.
Ultimate Iron Man - The art looks GREAT! I PRAY Card learns how to write between now and then.
Ultimate Vision - WOAH! Wait a minute, step back. Vision did NOT look like that. EITHER Vision. So, did Hank get horny and redesign her or something? Maybe Ultron'll look different too. . .I'm almost positive we'll see the 6-part story collected in the Ultimate Vision Limited Series or as a one-shot with Mad's cover, like E said. It'd be stupid to leave it alone.
Supreme Power: Squadron Supreme - I know it isn't Ultimate, but it might as well be. At first, I was aprhensive about the move, but I think it'll work well since they'll all FINALLY be a team. And there's defeintly more than the core characters there (Hyperion, Power Princess, Dr. Spectrum, Amphibian, Nighthawk, Blur).
I'm assuming the characters chasing down Hyperion join as well (Not that there was any real doubt in my mind. (Who I'm assuming are Nuke, Arcana, Tom Thumb, and ???). There are 11 people in the photo (Which looks hauntingly similair to the original Squadron Supreme TPD cover), from what I could make out. The 11th person might be the Skrullian Skymaster, but who knows? Point being: It'll be a DAMN good series.
