I only heard about it a little while ago. It seems to be a similar premise to the original Marvel Ultimate line (before Millar f_cked everything up.)
Scott Snyder is the "showrunner," overseeing scripts by such writers as Kelly Thompson and Jason Aaron.
To reiterate, I think Ultimate Marvel got off to a good start with the early Bendis/Bagley Spider-Man stories, before Millar took it down an ugly path.
Sorry there's no links yet (I worry about my device's security too much), but I'm sure others can provide them.
