Back in 2014, a mysterious advertisement for Sunset Overdrive popped up online (now preserved via NeoGAF), which said that the game was coming to both Xbox One and PC. The rumour was later debunked by Mike Ybarra, but now it's time for round two.
Industry insider "Enter the Dragon Punch" now claims that the game is heading to Windows 10. On NeoGAF he claims that the game is going to be a Windows 10 exclusive, and that this comes from a "solid source".
Make of that what you will, but Microsoft have been keen to port their Xbox One exclusives to Windows 10 as of late.
