both consoles are outdated , you will never see games like battlefield or god of war or any high budget big graphic game being run native1080p on either console they will however make more psn games in 1080p, they generally use much simpler graphics either way 720p native looks great as it is.
i expect new hardware to be leaked in late 2011 and releasing sometime in 2012 2013, i really dont see them pushing much more out of these boxes , i mean look at the games on pc in my eyes the consoles have been maxed out for a good while now, they just keep optimizing games but the reality is consoles will never have super high rez textures like pc nor will they display in 1080p with a steady 60fps or above framerate.
2 more years and we get brand new hardware its not a bad thing especially if the next set of hardware is at least 3 times as powerful thats about how much more powerful a recent gaming pc is to the ps3 and about 4 times more powerful than a 360, theoretical number crunching wise.
