you have a very nice girl friend ^^
as for the console decision .. well, you haven't really bought any of the big sony exclusives for your PS2, so I guess you aren't interested in their sequels
only for multiplat games the 360 could be the better choice
exclusive game you could try for PS3 are: Demon's Souls (not released in AUS), Valkyria Chronicles, Everybody's Golf (i like it very much :) ), Uncharted, Ratchet & Clank Future (Tools of Destruction is the first in that series - there are 2 more tiles released already, all for PS3)
upcoming exclusives: Heavy Rain, The Last Guardian, Modnation Racers, 3D Dot Game Heroes, Yakuza 3 (maybe?hopefully?)
exclusive 360 games that might interest you (list may be incomplete - I have don't have a 360): Fable 2, Mass Effect, Gears of War (possibly banned in AUS), Kameo , Banjo Kazooie: Nuts & Bolts
upcoming exclusives: Fable 3, Mass Effect 2, Alan Wake,
edit: all titles linked - have a look at some of the videos and decide for yourself
