Its not much info, but its better than nothing. Two things that caught my eye though:

1: A sequel, not a reboot
2: No recasting planned.

I have to say I'm pleased with both of those decisions. The movie origin, though I didn't like it at first, grew on me. And Eric Bana, I felt, made a GREAT Bruce Banner, so glad to know he's returning. Or they hope to get him to return, at least.
