Same people essentially complaining about GTA VI coming would complain if it wasn't. Like all games a year from now it should be Windows 10 exclusive, along with DirectX 11.3/12. No excuse other than bad porting to an old engine for this not to happen. Windows 10 is free for Windows 7 and 8/8.1 users, if they want to complain too bad, why should the rest of us be disadvantaged by their stubbornness. I've read comments of people wanting to stick to Windows 7 even though Windows 10 will be free for them. Complete lunacy. Most cards of the last few years support at least DirectX 11.3, any card not supporting it probably wouldn't be able to run modern games in a years time anyway. By limiting it to Windows 10 they won't really hurt sales, and make development and maintenance an absolute crapload easier.
