Two months...
...in the best of all possible worlds.
Two weeks...
...once all the kinks are worked out.
P.S. This is not a slam or a complaint. I saw xkcd this morning and couldn't resist. The Pandora release reminds me of the (old) Debian release cycle: it'll be done when it's done and not before. Considering the Pandora is a piece of hardware, and the difficulty of physical "updates," I'm quite glad of this policy. I fully expect to see my unit... in the next couple months. According to the table above, and what it communicates about the real world, I'd say the OP team is doing extraordinarily well!
