No offense to 360 players, but the PS3 version was really downsized in favor of "both versions being balanced with each other". SC3 had tons of extras, options, even seiyuu/voice acting tests, and the character customization had separate layers for belts and stuff...
...but all we get from SC4 now is just... a normal SC, with HD graphics. Story mode sucks, the tower is not really that good...and man...Darth Vader should be a customizable character. (The Apprentice is lame, Luke should've been added)
