I just found this on Resident Evil's official Facebook page:

It's still longer than I would have wished, but oh well, at least it looks like we'll get a really polished PC version with all the extras the console versions get, and I still have the new Tomb Raider to bridge the time.
We are pleased to announce that Resident Evil 6 will be available for PC on March 22nd 2013 and will include all the content found on the console versions, including 'No Hope Left' mode and Ada Wong's campaign unlocked from the start.
