Except GT has an enormous amount of potential, and is massive outside of Japan (and Europe is probably the biggest market for GT). Last generation, Polyphony sold 22,170,000 units of software on the PS3 - that's an enormous amount. Now, I'm not for one minute saying sales figures = quality, and I'm also not saying GT is perfect, because it certainly isn't, but I thoroughly enjoyed every GT game on PS3, and they all on the whole reviewed well. You would have to be absolutely, certifably, laughably bonkers to just say "you know what, let's stop trying to improve and continue to develop GT altogether and just go mobile". It would be a different matter if GT had no potential as a franchise, but I think we're some way off a future where GT doesn't exist in a traditional sense. I'm not saying it's too big to fail (and it can't ride on its past success and reputation forever), but the GT name is huge and will definitely help.
