TT was started by a bike-fanatic PD employee using GT4's engine, etc., etc.
We all know it was basically a sideproject which, although it was limited in content, was still a hugely impressive first take on a new genre.
I sure had a great time playing it and really hope TT2 will arrive before GT6, even if it were still just a sideproject with more bikes than the previous one.
Really hope though it will be a full game like GT5 is for cars, but i'm not sure they really could as the market might be smaller to justify all the resources for including, say, 750 or so bikes and associated content.
Think it makes more sense as a stand-alone title although some bike versus car interaction between GT5 and TT2 might be fun ( maybe online in some events, not sure this is even possible ).
Finally i want to point out there is a TT section on GTP which is extremely silent at the moment and with no confirmation TT2 will actually materialise perhaps some more regular visitors will start to get it back to life as TT2 is being discussed there.
Since PD seems to admit reading these pages, a bit more discussion on that section might persuade them there is still enthusiasm for TT2.
Wishful thinking i know, GT5 is coming and will demand all my attention for a while, and then suddenly there it is, the real riding simulation part 2.
