I think it will. Classic gameplay fits Halo much better.
Do you think Halo 3: Anniversary will mark the return of Halo?
A bit off topic but, if it comes to PC I sure hope it's not like H2V and H5F where they made you buy Microsoft's latest OS just to play an old game.
^This. But unfortunately it might be locked to Win10. I mean think about it, Halo 3 PC is something fans have been wanting for years and this would be a way that MS could help market Windows 10 use . Then again, who knows.
