I'd expect these parts to be embedded, with both the APU and GDDR5 soldered to the board.
I could see a socketed version of the APU, but I highly doubt there will be any non-embedded GDDR5

If by DDR3 format you mean 240-pin DIMMs, probably not.

The PS4 is rumoured to use only GDDR5, but the system specific programming for the PS4 can offset the latency issues.
Regular Windows performance should be horrible due to regular desktop systems being dependant on a low latency memory subsystem.
GDDR5 does not have significantly higher latency than DDR3. It has much loser timings, but this is largely offset by much higher clock speeds.
Any extra latency (and there may well be none) will be more than made with the bandwidth increase, when it comes to the tasks these parts are oriented for.

No. GDDR is no more error prone or tolerant than DDR. Consumer GPUs don't tend to have ECC, but neither do consumer CPUs.Edited by Blameless - 3/5/13 at 8:44am
