PC gamers need some Quantum Break too.

Considering Remedy, it's very probable that a PC version of QB will come. What I highly highly doubt is that it will release the same day as the Xbox One version, which is what these late rumors are suggesting.

I think the expectation has always been that QB will eventually release on PC at some point. I'll be very surprised though it if releases simultaneously with the XBO version.

This is like the 20th thread about the game coming to PC, lol.

Lake has said multiple times he wants the game to come to PC. Their other games end up on PC. It's going to come to PC. Probably even day one.

Pretty much this.

Yeah, didn't expect anything else. Same day as Xbox One version.

Basically everything the Xbox one gets, ends up on pc.

It's been confirmed now the embargo is over:
