I don't buy any console for one game.
If all the games you want are basically 3rd party, then just wait for WiiU.
If you want quite a few first party PS3 games, then wait a month to verify if there will be a price cut on PS3. (I really think there will be soon)
OR just buy one of the used PS3s on craigslist or Ebay. Tons of savings there too.
Again, I'd only buy a console if there were four or so games I wanted to play and they were only on that console.
