Last year the same thing happened with one of my friends....
then he cam over to my house n played on PS3....was very impressed....he actually said Resistance looked better than GEOW (I was like WTF...but stayed silent)
2 weeks later he rings me up n say "hey I got a PS3, whats your PSN ID"
he had a PS1 & PS2 but went for 360 as it was cheaper....I think GT 5 prologue helped to turn him over...but the FF13 trailer was the last nail in the coffin
