So, to recap: Microsoft is working on a karaoke game codenamed "Lips" – that's a rumor. The developer working on the game is iNiS – also a rumor. That iNiS has a long history of making music and rhythm games and that it's co-founder Keiichi Yano confirmed that the developer was in fact working on an unnamed Xbox 360 game – those are both facts. We'll (hopefully) put the rest of the puzzle together four weeks from today when Microsoft holds their E3 press conference. If you've got any more information, we're all ears about Lips.
