The argument iwas not valid in 2009 as game sizes were usually under 20Gig, now they range between 10 and 50g, making 1-5 xbox discs (2010). Some cut scenes and some lower res and less bonus material have kept things with in managable levels. 2011 will be the tell tail when sony will have PS3 games on 2 and 3 bleu Rays (New Massive 1080P games) and if they are multi platfor games, then that will translate to up to 15 discs for the 360...... Im smelling the forcing factor for an early 720 release
