Capcom Confirms No Pre Order Option Available On European PSN Store
Unfortunately a pre-order for Resident Evil was not possible on Sony platforms. We are therefore offering cross-buy to anyone purchasing the game via the Sony Store in the first two weeks on sale. This just in from the Capcom Blog.
So there you have it, Buy Resident evil on PlayStation 3 or 4 and get the other version free for the first two weeks.
