Agreed.
At this point my only hope is influence of Polyphony Digital. If Kazunori wants to have legacy-standard support on PS4 for GT7, he is the only one who can influence Yoshida and Hirai to make it happen. The recent talks from Rushy - and he is the only one talking at least something about support - are not doing much in clearing the confusion.
Problem is if someone is already making a new standard in veins of TouchSense - which is already more than 13 years old - that will provide with much greater frequencies and other haptic/FFB possibilities. Also, maybe both Sony and Microsoft are fed enough with paying Immersion Co. with the royalties for licensing TouchSense in both controllers and consoles and they looking to move away from it (all PSone/PS2 and PS3 controllers with rumble features and both Xbox and X360 controllers are actually using Immersion Co, patents). And new generation could offer them a fresh start.
With Logitech out of mass-market, the actual availability of the wheels as peripherals has drastically shrinked (shrunk?). Only few years ago anyone in even mid-developed countries could go into the first supermarket and come out with either DFP/DFGT or go into the nearest tech-store and come out with G25/G27. With logitech out, the wheel market has drastically changed. Thrustmaster T500RS can't be compared with those wheels, solely because of the price. There is no "impulse buy" for something that costs 400€, opposite to 200€ for DFP back in 2004, for instance. Also, shelf-presence of T500RS is non-existant compared to Logitech models in the past.
I don't know. There is so much to lose for many, many, many people if next-gen (particularly PS platform) will not support legacy-standards.
If that happens, it will take many years to re-establish the same saturation with the wheels and one serious part of drivers generation could be lost in the process, simply because people will not be in situation to justify the purchase of new standard with already hundreds (and thousands) spent on products bought simply because it was "logical" to think they will span over at least one more generation.
