I think some of you are being really silly about the framerate. You can see from the videos of it running on a 3DS that it runs pretty smoothly. After all, the IGN videos are magnified significantly, and probably aren't running on an actual 3DS. All these previewers seem to be pretty impressed with it visually. I think you're getting upset over nothing.
Anyway, the Simon footage looks really fun! It also looks like non-major enemies will be easy to take down, especially when compared to the non-major enemies from the first game. They last long enough to get one or two combos in, if even that long. Also, the map makes sense now. It represents the area you are currently in rather than the whole stage. I wonder if there is a way too look at the entire stage map during gameplay.
Also, I wouldn't assume that a second version is coming out for consoles just because of that one source. While the quotes from Cox may be entirely true, that doesn't mean that Mercurysteam will ABSOLUTELY release it for consoles. He also says that they have an exclusivity contract with Nintendo. Also, if the game doesn't sell too well on the original platform (3DS), then I can't see Konami giving another release of it the greenlight. Nothing has been confirmed there, so I wouldn't get my hopes up.
