It's 3:00 am here but I can't sleep because I got such a brilliant idea while thinking about this whole Bayonetta 2 case.
Bayonetta 2 is published by Nintendo so it almost surely will never be ported to another system BUT Sega still owns the Bayonetta trademark, which means they only grant license to Nintendo and PG to make Bayonetta 2. It also means that Sega can decide to release another Bayonetta game ANYTIME.
Here's what happens : Sega knocks at Platinum Game's door and says "ok guys I know you're losing millions with that WiiU only Bayonetta 2. Here's what we do : we develop a Bayonetta Σ2/2'/ 2 complete edition or whatever on PS3/360 and we change that pixel here so we get A DIFFERENT GAME from the one Nintendo published, thus plainly legitimate juridically speaking". Needless to say, such a scheme would drive the game's profitability significantly up, which would be extremely beneficial to Platinum Games.
So what do you think of my evil plan, which I've already submitted to Sega?
