The higher level backers pretty consistently request that he takes a break after release in hopes that he doesn't get burnt out. I wouldn't say I'm an expert, but based on previous releases I think it goes like this:
2-3 weeks before beta release - crazy work
beta release - crazy fixes
first and second releases - normal work
week-ish before public release - relaxed work
public release - normal work
1-2 weeks after public release = break/minimal work/planning
Then the active dev cycle starts up again. But yes, from what
Gladheim said... August beta release is likely, with a public release in mid to late Sept. Unless he decides to make it an even
bigger update. lol
