According to TheSixthAxis, the follwing screenshot looks to us like when the new 2.40 Firmware update rolls out you’ll be graded on how many Trophies you can obtain per game on the PS3, rather than just a flat out points system an the Xbox360, and we’d imagine anyone going for Platinum on the PS3 games then get practising

As i own both consoles, if this rumor and screenshot is anything to go by then it is a fresh way to approach the Achievement/trophy system.
