[citation][nom]stowie[/nom]Does this mean 3d blu-rays will be incoded in 1080i for each offset frame, if so why the need for special equipment, why can't any 1080p at 60hz work?[/citation]
I imagine it could, but remember the player has to process twice as much data. this also means that data will have to be able to be read twice as fast from the bd drive, this is the biggest worry, currently a single bluray video stream can reach peaks of up to 50mb/s, but the ps3 (and im sure many other standalones) only has a 2x bluray drive, max speed 72mb/s. they may be able to achieve better compression as the two streams would be very similar, but they may have to compress the movies more in order for them to be playable in 2x drives.
The ps3 does have the added advantage of alot of memory, which it could buffer data in order to overcome these peaks.
As for video output, I see no reason why any device capable of outputting 1080/60p wouldn't work. it does mean we loose the niceness of 24p tho, unless there is a 48p standard or something already built in, otherwise just do pulldown to 30fps like with dvds, then 2 of them make 60fps.
