You doubt this?? Tell you that you are aware that games "get bigger". It's mantra...everyone knows this. 360 sealed it's fate with a shorter lifecycle when they went DVD. How many big PC titles are made on CD? They all jumped to DVD...you wouldn't buy a PC to game that has a CDROM drive. No, you'd have to upgrade a lot sooner because big PC developers will leave you behind a lot faster. They didn't say "Well almost every PC has a CDROM drive but not every PC has a DVDROM drive...let's make our games CD size"...no...they keep going with bigger games.
