Italian website multiplayer.it recently held a video interview with GT5 creator Kazunori Yamuchi when asked about the possibility of personification of the game ala Forza Yamuchi stated it was a posibility but the team was focused on GT5 Prologue.

All technological requirements to render collision in GT5 are already in place and therefore technically not difficult to implement in the future.
-The possibility that GT5 may allow the customization and trading of vehicles "a la" Forza Motorsport
-Episodic content (i.e., updates) may be possible in GT5 although they are currently focusing strictly on Prologue at the moment.
-Polyphony is currently not entirely satisfied with Prologue's current online play, although they hope to address this in a fall update.
-In direct response to the interviewer's question: Polyphony is yet to determine how they will enrich the single-player experience in GT5 compared to earlier GT versions, although it is certain that the game will see the return of the Licensing system.
-Although the game is currently utilizing the full potential of the PlayStation3 (i.e, accurate vehicle physics, models, etc.), minor improvements will be made and evident in the future.
-Working toward releasing GT for PSP within the vicinity of GT5's release...and there may be some form of integration between the two versions.
-Kazunori Yamuchi finds it difficult to play any racing games (namely: Forza, Project Gotham) other than Gran Turismo [NOTE: Interpret as you see fit!]
-Kazunori Yamuchi favorite vehicle is the Ferrari 330 P4, although he unfortunately doesn't own one.
upon receiving a private message from Torch I would like to make a correction to the title.
ey Lord Anibus,
In response to your motorbikes statement:
I took a look at the video again, and I want to confirm and clarify that they are not referring to adding motorcycles to GT5.
To be specific, the interviewer mentions how Polyphony has made other non-GT5 racing games, namely Tourist Trophy, Motor Tune GP and Omega Bust(???), and asks whether there will be next-gen iterations of said games...given that the Italians are huge fans of such [motorcycle] games, new versions "wouldn't be too bad!"
Kazunori Yamuchi replies that Polyphony's technology permits them to do many things, but that they [Polyphony] first need to find the right idea and the best design.
Therefore, I regret to break it to you that I reckon that GT5 will likely not be seeing any motorbikes...on the bright side, we may be seeing some nice dedicated titles instead.
Hope that helps.
