to be honest box xbox and ps3 are actually fairly decent consoles. both can improve massively and not just in terms of polygons being shifted.
they need to learn some lessons:
:: p2p for multiplayer is shite - most games require dedicated servers - even 1on1 someone has a massive hosting advantage.
:: a mouse needs to be FULLY supported. i refuse to play fps on a console due to the useless pads. i know both allow basic mouse usage but they need to support gaming mice with thumb buttons. they also need to be fully configurable. i know there are mouse gadgets but they try to rectify the acceleration and fudge it. it would also be nice to play with PC on the same servers (another reason they need the mouse and not the aimbot pads)
:: both need to be able to read and write to NAS boxes and be able to sort right (for some reason my ps3 fails to list albums in order on my nas box - i dont use the useless itunes method - i store under genre then artist then album. no use to me listing like in itunes as it moves the music all over the place, any colaborations get mixed up and its a total mess for people with many albums (we have laborously moved all our albums over to a NAS box)
:: both need ALL GAMES to play in 1080p or higher. so many games are upscaled on both consoles. often looking terrible
:: both need considerably more RAM. why both have such small amounts amazes me. it limits them no end. and due to multiplatform issues, PC gamers are suffering with poor ports and console limitations.
im sure there are more but not finished my coffee yet
