Those "value packs" would be the shops' doing, not Sony's. If you have your preorder in now make sure they aren't getting you sucked into a bundle.
Hmm, 700K units for North America at launch? Going to be a bit tricky to find then, that gets spread very thin across the US and Canada (if his numbers are true, I don't think anything official was ever announced so it's speculation on his part). I may wind up waiting a few months before snagging one.
