I didnt want to bury this new info in the other thread. These are OFFICIAL specs from Sony themselves. So yeah, the leaked specs were pretty accurate. Even the ridiculous bit about Sony trying to bring the RAM upto 8GB from 4GB. Insane.
These official documents contain a lot of info on practically everything about the console.
I think this pretty much rules out a $300 console. It also puts pressure on MS to match Sony's specs. Stakes have been raised.
