For the record, I have no official press release in my inbox and there's no verifying link in this source. However, it all seems perfectly plausible, so…
According to Pressa2join.com , Square Enix has announced general launch windows for the release of Rise of the Tomb Raider on PC and PlayStation 4.
It seems Windows 10 and Steam will get it in early 2016, while PS4 players will have to wait until Holiday 2016. This would give the anticipated Tomb Raider sequel a year's worth of console exclusivity on Xbox platforms, which is about what everyone expected. And of course, when the game comes to PS4, it will undoubtedly launch with a few updates and maybe some extra content. It's the way of the gaming world.
Personally, I'm fine with waiting. I think I'll have more than enough to play in 2016 on PS4, thank you.
