I don't believe it's speculation on future planning. Capcom Guy is saying that it is really happening. I'm glad that older thread with Capcom Guy was found to help back up his validity.
I suppose we can only hope it gets announced at TGS this year.
He basically just goes on showing the development kit and tries to explain the Tekken joke half the time. The thread has hardly anything about his claims aside from Legends 3 at E3. According to other fellow /v/ goers however, he mentioned the following in a separate thread.
Dark Void will be the next Bionic Commando - By next, he means hyped up gameplay that won't deliver in retail or critical acclaim.
Marvel vs. Capcom 3 - It's in development, but won't be announced for quite a while yet.
A New EXE/Starforce game - He did not specify that it was a cross over, just grouped them together as if they were the same game.
Only thing that came true was a new EXE/Starforce game, which was the cross over. Dark Void and MvC3 though...um... yeah. Whether he had more claims, I'm unaware of however, but that's all I got at the moment.
So at the moment, his credibility is still up in the air.
