I'm too pesimistic to read "a couple" exactly like 2 weeks, though that would be awesome.
I agree that some surprises for the update should be kept, but we really have a bunch of animals - so one or two more examples before release, if the update is more than two weeks away, would be cool. In general, I'd love some info crumb every two weeks, and may it just include what bugs they are currently hunting. Could also ease out some frustration with the issue tracker.
Typically an announcement doesn't come long after a teaser like the one we've received, so hopefully we won't have to wait too long for more information!
