I would also be interested to hear about this.
Frogboy has posted a tentative schedule
Here's my take on it
You have to be realistic as to the trade off between
Functionally it's an alpha. But it's still available to a lot of people. So you can't just roll out patches like you would internally. If your code crashes and melts your face off internally, that's ok, but to external players, that's not that cool. So there's still some semblance of 'hey lets at least do a minimal passthrough testing before giving it out' thing between patches. So you can't functinally roll out patches reallly quickly without sacrificing the testing aspect.
Rolling out patches quickly also makes it feel like you're on a treadmill from a development perspective. Wanting to do nly small changes rather than addressing large sweeping issues that might take a month of planning and dev work.
Thus I think realistically it makes sense to see large patches happen maybe 1-1.5 months. Then hotfixes in between to address critical face melting problems.
I think it would be nice for Stardock to have an "Experimental" beta channel. A place where they can roll out new features for users to test for those who want to be on the 'cutting edge'. But with the understanding that save games could be incompatible, hardware issues could arise, etc. I realize it seems like we're doing that right now, but again, it's important to realize that even as an alpha customers do have an expectation of the game not exploding when you hit Start.
