UPDATE: The Halo Master Chief Collection will soon be getting its eagerly-awaited release on PC at last - and it's sooner than you think. In fact, the Halo Reach PC release will actually be December 3 - less than three weeks away.
This was leaked earlier today but properly announced at X019, but unlike suspected the Xbox One version of Halo Reach will not be coming today - instead it will arrive at the same time as the Halo MCC PC release in December. Good news all round.
This news was spotted by True Achievements, but is easily verifiable. Just last night, Microsoft changed the PC version of Halo Reach as down for December 3 - and confirmed it at X019.
The final beta testing for Halo Reach on PC is still going on right now, and has been extended multiple times - so it's great to get a release straight after the testing has concluded.
Halo Reach on PC - and the first part of the Halo Master Chief Collection PC version - will be out, at long last, on December 3.
