If you really want a PS3 now this is a good price.The best PS3 deal I've seen was from Black Friday last year where you could get the 250GB Super Slim with Uncharted 1&2 and Infamous 1&2+DLC for $200. No one knows if Sony will ever announce a price drop for the PS3, they recently announced a God of War bundle with the PS3 for $350 (6 games total I think). For all we know Sony could just announce more bundles with more stuff to keep the prices high.
This is a much better deal than that Black Friday sale. This is for the 500gb hard drive as opposed to the 250gb and it comes with Assassin's Creed 3 in a real package and not some paper cases that Uncharted 1, 2 and Infamous 1 and 2 came with.
