PS3 Uncharted Drakes Fortune looked way better than this does, and it's a year old now. I might pick it up on PS3, but DLC certainly won't influence what platform I buy it on. In fact, I still don't understand why Microsoft wasted $50m on the GTAIV 360 DLC, as by the time it arrives, nobody cares anymore...

I certainly don't. I might pickup the PS3 version, I'll see if the reviews pitch it anywhere close to Uncharted, otherwise I'll pick up one of the other great PS3 titles this season.
