This is just a draft, and not finalized yet, but it's worth a look http://people.mozilla.com/~sayrer/2011/temp/process.html Obviously a 6 week cadence isn't something we can support, but it's worth watching how this transition ends up playing out, I think.
What is our current status with respect to releasing 1.5? Have we reached consensus on the 10.6 issue? If someone merged in the 10.6 branch on Monday afternoon, how outraged would the thread be? ;) -Colin
