I don't think Sony will be quick to drop the price of the PS3, as I don't think they're still trying to win the war and are more interested in being short/medium term profitable. So, only if Sony recovers from their financial woes and the PS3 stays on the market for a long time.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
