At first I thought this was great and was going to rectify that problem where the PS4 digital and retail versions are the same price. Then I realized it was for the PS3 digital version only which is the cheapest version and now they're getting a free game with it as well if they pre-order lol.
Your interest is irrelevant. Konami is well aware that if you go to biggest stores in Switzerland right now to buy PS4, they will take your preorder and say to you to expect console to arrive in late May/early June [in EU shipments are so small and thirst is so real T_T].
PS3 version of the game will sell much more than PS4 version.
