Uncharted is one of the most underrated games on the PS3 in my opinion. I bought it at launch and completed it shortly afterwards. The slight change in pace in the last level really caught me off gaurd but was awsome. One of my favorite games. Bring on trophies.
PS3 FTW guys. Plus I've always associated Final Fantasy with the Playstation brand. Its one of the reasons the PS1&2 were so popular. But too be honest. Its really not going to matter. I think sales will be split right down the middle between 360 and PS3.
