Yes, saw that. Apparently there are multiple file placeholders that say "DrOctopus" in addition to Jill, Shuma, and Frank. Perhaps the Electra rumors were off, and DocOck was the character yanked out late to even the roster when Frank had issues. There was no real evidence for Electra, but there certainly is for DocOck now.
I'd be thrilled if this comes to fruition. The game is noticeably missing a Spidey villain, and Dr. Octopus is a perfect fit. A classic Marvel villain, and he'd fit in with the storyline (um, what happened to that Capcom?). That would pretty much fill out any wishlist I was realistically hope for for the roster, well except for Sentinel NOT being in

Actually I do love the Green Goblin, but can't really expect him and Doc Ock, so either is a win.
Yeah, BBCS did this so well, especially the demo combo option. They should have copied it.
I'm beginning to think this game need more dev time, it was pushed up to get it in Q1 for financial reasons, and some of the polish suffered as a result. Hope they can patch some of these omissions, issues.
