Well, I finally got my PS3 version this evening after a load of pissing about with order "delays."
Looking on the bright side I had 30 days to return the 360 version so I was able to make sure that the PS3 one was definitely coming. Also they didn't try to charge me full-price after i pre-ordered it at £53 . . .which was a good price, all the dicking around notwithstanding.
I still think Amazon pulled a flanker here by sending out 360 as a placeholder because of a PS3 shortage. Personally, I'd have more respect for these corporations if they just told you the truth in the first place.
I just hope the 2012 CE season brings better online pre-order competence because this year has sucked, quite frankly
