I thought it was extremely difficult to get decent emulation with only a 1 generation difference in hardware.
As far as PS360 streaming goes, for all multiplat games streaming can be the PC version of the game, so they can use standard PC servers. PS3 exclusives would run best on standard PS3s. Hells there must be hundreds of thousands of used PS3's going cheap, probably be cheaper for Sony to get on E-bay and buy up a bunch of cheap PS3's than to go manufacture fresh C3lls, heck it must be possible to buy a used PS3 for $50 now that the new gen has arrived. $50 million gets Sony 1 million PS3s. How many PS3's would they need? a million? will there likely to be more than a million people all online at once wanting to play PS3 exclusives? I doubt it. As long as Sony uses PC versions of 3rd party multiplats they don't need huge numbers of PS3's for streaming.
