Engadget had a intresting piece of information come across their site.
The PS3 may be getting an Uncharted 2 bundle with a 250GB PS3. Endgadget said it was from a reliable source, but for right now we will leave it as a rumor just to be safe. No price point or release information was given. But based off the rumor for Europe that includes the same bundle, I would take a guess it will hit some times in October if its real.
