I looked for the problem online, and it appears that the PS3 version will be automatically downloaded on release day. Already happened for other cross-buy games as well.
Have you got a souce? What other games were released with Cross buy? Im so scared right now. First time pre ordering and this happens, aspecially with a game that I really want! I hope that i'll still be able to download the DLC costumes for my PS3. I thought that after when the Vita stuff were downloaded, the PS3 version would start, but no.
I sent an e-mail to Sony Playstation Support (UK), I'll write down the responce here.
LOL you just spoke the exact words in my head dude
Looking forward to hearing your response from Support. Please post it here for people like me who are also having this exact problem.
I pre-ordered it on the PSN store. It gives you both the PS3 and Vita version but so far only allows you to download hte Vita version. Hope that clears up any confusion
