I think its already happened. A big complaint about this years E3 was that there were almost no new games announced at the press conferences, just a lot of updated looks at known quantities. I think the big hardware and first party games will still be saved for E3, but big third party franchise announcements will start going to the VGAs.
I heard you don't take damage in pandora mode. So if an opponent ever uses it, all you have to do is run away for a couple of seconds then pop off your own pandora mode and you will automatically win because your opponents health will drain before yours. Also, Fuck Gems!
Nemesis seems about what I expected but damn Dr. Strange looks beast. He looks like a Magneto who can teleport and has traps. Can't wait to see what the rest of the "unannounced" characters can do.
