You don't need the PS3 version, the PC one works just fine (and it's a lot cheaper!).

I'm a 1.0 non-legacy player and I simply bought the new 2.0 PC game. I used my 18 character pre-order code on the preorder site which then gave me the 20 character code and sent me to the MogStation website to redeem it.

I redeemed it on that site and it clearly showed the breakdown of everything already on my 1.0 Collectors FFXIV account (Onion Helm, Asuran Armguards, all the new 2.0 collectors items etc) and then it showed it was going to be adding the Pre-Order code with Mog Cap and Cait Sith Doll Minion.

I can log into game and get the same "wait for early access" message as everyone else, so I don't see any problem with it

Don't be doing that order and cancelling it thing that someone suggested... that's fraud and will probably ruin it with future promotions if people take advantage like that.
