Beta and pre-order pages are live: only lists PS4, XB1 and PC, pre-order page lists PS4 first (all previous game listed Xbox consoles first): https://www.callofduty.com/blackops3/beta for the beta page, https://www.callofduty.com/blackops3/buy for the pre-order page. The pre-order for PS4 says 'Only on PlayStation' XD
