We've known there will be DX11 support for a long time now ala Nathan Camarillo. Everyone who was pitching a fit before is just retarded and wanted something to complain about.
So at the end of the day, we know nothing more than we did 1 week before the release of Crysis 2.
True to some extent, but this announcement makes it even more official. Plus, the forum won't be polluted with DX11 topics from now on. Some peace and quiet for both moderators
I think it will be a matter of weeks before release, if done well. Maybe months.
