Hopefully they'll do it.I thought the idea was that they were updating the whole system to improve some of the latency issues?
As of now, Remote Play is poor, and it runs at PSP resolution. If they really want to make Ico/SotC run at 852x480, they have to improve the system.
I'm sure Gaikai tech will come in handy (that Instant Play feature on the Video Store probably has something to do with it)
