and apparently if you are a PS4 user you will get the upgrade for free if you own the ps3 version. If anyone buys the link above and has been a PC player, post here if you get a free month of the game or not. Might be worth it if $10 gets you ps3/ps4 and a free month, since thats all you will probably need to see the new patch stuff in 2 weeks.
