As with all timed exclusives the one around Peggle 2 will expire next month as EA announced during PAX 2014 that the game will be coming to the PlayStation 4 on October 14th.
The PS4 version will be the exact release that the Xbox One and Xbox 360 players have been enjoying for the last few months. That's not a bad thing as Peggle 2 was a pretty solid (if safe) experience from looking that review scores when it came out.
