As for an IM@S SP 2, it would be nice to see better lip-synching and have more unlockable outfits and accessories, as well as more creative DLC and IM@S 2 outfits. If the 3DS or NGP have enough memory, maybe it would be possible to see duets on stage. Although I don't want it to take after IM@S 2 or be based off of the IM@S 2 storyline, it would be nice to see songs such as SMOKY THRILL, Little Match Girl, The World is all One, and IM@S 2nd mix as well.
I would like to see new rivals introduced, and as much as I like Jupiter, they should be female this time. I think it's about time they introduce new female characters to the series.
Also, I'd like the game to still be from the Producer's perspective, although if it was from the idol's that would be cool too. The idea of an IM@S-Break-based game just doesn't appeal to me that much. The harem-idea gets old fast...I only read the manga because it's IM@S.
And Yukiho's adorable in it.
And...maybe an appearance from our 876 friends? It could happen on the 3DS...
