What changes do you want in the Xbox 720 and PS4 compared to this gen?

Instant restarts. Give the consoles enough memory so I don't have to wait upon death or when restarting a race. Racing games could do this in the previous gens, seems that ability has been lost.

Game sound to be sampled in 44.1khz or rather even 88.2khz instead of 48khz. Standard ability to play your own soundtracks directly from CD or after lossless CD ripping and correctly decoding pro-logic surround sound from the audio CDs.
Now it's not really worth it, the ps3 hardly has games that allow custom soundtracks and if it does only through compressed mp3s that then are also resampled from 44.1 to 48khz. The 360 does allow custom soundtracks but adds another layer of output compression. Either way pro-logic surround sound from the original CD is lost.
96khz/24 is fine too, give me some HD sound with the HD picture.
