Didn't see a Gamescom thread so I made a separate one. Anyway, what are the odds of that? A lot of people were predicting one at E3, but one didn't come. I didn't think there would be one at E3 since the MW3 Bundle was just released. Last year a lot of people also predicted one at E3 and we ended up seeing one at gamescom with the Infamous Bundle. I'm really hoping for one since I could use a 2nd one and there don't seem to be many deals out there.
I would guess the odds are zero for a price drop on the existing PS3. I'd think chances are higher to see the announcement of the new slimmer PS3, and/or a something new with Vita.
The slimmer PS3 could have a price drop... I wouldn't expect an announcement of a price drop until it actually happens though. Otherwise it just cannibalizes current sales because people decide to wait for the price drop.
