Alpha's ruled out thanks to the mini-series announcement. I detect a lot of theatrics and trolling going on regarding both the events of 700 and Superior Spider-Man #1 myself. For once I don't trust what Rich says. He could very well be right...he doesn't seem to care about alienating people in the business or any of that stuff.
I don't think the Ben Reiley rumours have gone away. They've just been replaced by the Miguel rumours which are more popular. I'd be happy either way. I'm still trying to figure out the "it's someone we've seen part".
