To clarify I am very happy with where this generation of Playstation consoles is heading (I never owned a PS2, due to the lack of HD output, wired gamepads, limited audio support, limited online support, etc). But in the past on forums I recommended:
1) PVR/DVR support for the PS3. PlayTV and Thorne are basically what I was thinking of. (albeit I prefer a PS3 with this built-in)
2) I stated I thought it would be great if Sony would release a Nintendo Wii style controller. And Playstation Move is exactly what I hoped for, it can do everything the Wii-mote does only faster with more precision (of course it can also do more as critical in one of the points below).
3) I discussed the potential of implementing anti-aliasing on the Cell's SPUs and I discussed my preference for what type of AA I prefer (edge blurring like done in top antimated movies, so AA doesn't degrade graphics which do not need AA). Sony's enhanced implementation of MLAA does exactly this and the first results in God of War 3 were amazing. Now upcoming high profile exclusives such as Infamous 2, Killzone 3 and LittleBigPlanet 2 are confirmed to take this approach!
4) For the long run I wanted Sony to take the a 'virtual reality'-like route. IMO combining headtracking and stereoscopic 3D gaming (like done with past virtual reality solutions) with the Playstation Move controller (full 3D control) we are moving well into the right direction with regard to such wishes. IMMERSION AHOY!
I am talking about wishes outed publically in yesteryear discussions by me! 8-)
P.S. Sony has released a cheap TV with a PS2 built-in, in the past I stated I would like to see a HDTV with a PS3 built-in and preferable a Playstation eye or two. Make it happen Sony!
