From twitter:
The final number of tracks hasn't been fixed yet - KY
The VTEC sound had been reproduced ever since GT1, it switches at proper range according to cam profile ^KY
There might be something from LMS or ALMS could be added. ^KY
I don't think Bernie Echolstone won't allow F1 ^KY
Regarding interior view...do you mean you would want a black frame interior view? ^KY
Can't talk about details on customization but yes, you'll be able to customize. ^KY
Customization in GT5 will be better than GT4. ^KY
Most of the Civics from the 90's and on should make it into the game. ^KY
I drove the Honda CR-Z on the Honda test course in Japan and it handles really well. ^KY
f you go into a corner with good amount of load on the front tires the rear slides at a very controllable rate. ^KY
Technically it is possible to have bikes in the game but haven't really thought about it yet. ^KY
Regarding weather effects...rain, etc... Maybe. ^KY
There will be a lot of cool lounge and jazz music in the game. ^KY
Unique music for each manufactuer would be something cool to do. ^KY
By blackframe, I meant same as in PSP (re: cockpit view) ^KY
In that case, it would be technically possible. ^KY
What kind of things did the last part of the movie trailer with Red Bull make you imagine? ^KY
@GTPlanet I like you too! ^KY
Thank you all very much for joining. Please look forward to November! ^KY
Well that's it
