I've had a slightly irritating thought.
The thing about GT games is that they always sound stunningly good on paper - take GT5, for instance:
1000 cars!
Rally!
NASCAR!
Damage!
Course Maker!
Dynamic time!
Dynamic weather!
Sounds tremendous, right? However, the issue with GT is not in the ideas department, but the execution bit of the process. Now, look at the list of ideas again, with the caveats that come with trying to incorporate them into the game:
1000 cars! (200 of which are PS4 ready, 800 are PS2 quality)
Rally! (A smattering of current rally cars, no real point to point courses)
NASCAR! (only two locations, Daytona and Indianapolis, 16 car grids maximum)
Damage! (varying levels of damage detail depending on the car, some have detachable parts, standards get smudgy scratches only)
Course Maker! (no control over actual layout, minimal adjustments allowed)
Dynamic time! (not on all tracks)
Dynamic weather! (not on all tracks)
My point is, we've only had the "on paper" announcement for GT Sport - a next-gen racing game with more focus, less bloat, more consistency of visuals, eSports components supervised by the FIA, new cars, new sounds, better damage...
It sounds great. It could very well be great. But didn't GT5 sound oh so great when it was initially revealed? With that in mind, what will taking GT Sport from the idea phase and making it an actual game actually entail? How will the brief that has been laid out for the game actually be achieved? Things like how the damage will be improved, how the sounds will be improved, how will it really simulate real motorsports, how will the AI improve, and so the questions go on.
I know from my own life and work that the great ideas that I have are all well and good, but if they can't be done, they can't be done. Sadly, that's something Polyphony don't recognise - they have all these wonderful ideas, without consideration of how to practically and realistically make them work. It all sounds great at this point, because it always does, but we need to know the practicalities of it. It's something seemingly lacking in official explanation and discussion so far, and hopefully, it will be brought to light soon. The beta, perhaps, will hold some clues as to how this whole thing will work.
