I was thinking that's be a good title if the sequel had duel protagonists.
As for this teaser though, I'm really not sure how I feel about it. It does seem to hint at a sequel, but if that sequel ends up being an iPhone/iPad exclusive like Remix was then I'm gonna be straight-up pissed.
Hopefully whatever this thing actually is ends up on the 3DS. I was planning on getting one soon anyway. But right now, I'm just not going to get my hopes up.
I was as pissed off about the reveal as everyone else, but I'm still gonna end up buying the damn Remix. My favorite game ever with improved graphics right on my iPod? Gotta get me some of that, even though I would have obviously preferred a sequel.
I'll probably end up buying the iOS version out of blind loyalty to the franchise. And I really wonder how they'll make the combat work with both characters on the same screen, with no D-pad to control your partner.
