If your originaly of the PC version but have a PS3 you want to play on, you can still preorder and SE will send you a code. You go to <preorder.na.finalfantasyxiv.com> and they'll give you instructions of you have the promo-code from w/e you paid for it,etc. Gamestop. It's working as intended today!
Redeem your preorder code through SE first, then they'll give you a code to take to the PlayStation Store.
This is so I can download FFXIV:ARR for free before release. It makes sense if you have the right timing though!
I followed the instructions to go to the Playstation Network to enter the 12 digit code SE gave... but they're down for maintanence from 12pm to 6pm PST.
Way to take a page from SEs book guys! XD
