Games Radar do a few case studies to find out why the PS3 games are always late:
"Oh PS3, you really must work on this tardiness. You're a strong student with a lot of brains, and you can produce good work when you put your mind to it, but with this persistent lateness you're not only letting us down, but you're letting yourself down too. We know you've only just joined us and that you've had to take some time to settle in, but you're really going to have to start applying yourself from now on.
Nagging teacher-speak aside, just what is it with PS3 release shedules? Launch dates for games on Sony's black monolith seem more likely to slip than a fat man on an ice rink. Multi-format releases often see the PS3 version turning up to the party around midnight with a sheepish grin and a story about a train cancellation, and even exclusives have trouble arriving on time."
