I hope the guy is right, but I'm just starting to wonder how credible this stuff is after the whole Ninja Turte rumor. That and the bullet points just don't feel...I don't know, right, for lack of a better word. They don't give any tangible stuff. Also, it would have been nice to have some idea as to why this could have been just a conceptual idea; I'm guessing that whatever Retro is making, it's been in development for quite some time now, and way past conceptual ideas, and if he knew about this rumor for a couple of weeks, then why would he share something that is really old? How is this project something "everyone wants [Retro] to make?" I'm pretty sure there was no huge SF/Metroid crossover clamoring.
Some stuff just doesn't add up quite right to me.
