In today's 2.0 status check call, Daniel Beck as 2.0 release manager had raised that we still have too many issues in flight and it's unrealistic to expect that we can fix them all in RC. So we decided to add one more week till RC.
Then we realized that this is exactly the same thing that happened with beta. So it looks like it'd be a reasonable estimate that RC to release is going to need 2 weeks, too. That way we don't have to make a fool of ourselves by slipping it once again two weeks from now.
That brings the updated time line to ...
April 6: Create first release candidate (RC)
April 20: Create 2.0 proper release with last RC
April 26: More coordinated launch marketing activities commence
