The cheapest version of Sony's thinner PlayStation 3 is now 40GB fatter in North America, a "just announced" improvement now shipping from retailer GameStop. The better news is that it's still $299 USD.
GameStop is carrying the upgraded version of the console now, seemingly a replacement for the base 120GB model that has been on offer in North America. Sony has a press conference scheduled for Tuesday at Gamescom. So don't be surprised if a few more things are "just announced" soon.
Update: Looks like GameStop has yoinked the listing for that newish model of the PS3. Perhaps that announcement wasn't ready for prime time.
