At VSLive! San Francisco, I had the chance to spend some time with Don Box, Product Manager for Indigo. It was a very interesting conversation, and Don is quite a character. Here's an excerpt:
RWM: Where does this Indigo CTP stand on the Road to RTM?
DB: This CTP will be followed by Beta 1, and there may be CTPs between Beta 1 and Beta 2, as well as probably one or two more between Beta 2 and RC1. There probably won't be any CTPs between RCs, God help us if there are. :). The goal is to keep the flow going as much as possible, and getting the world of Microsoft set up to do that.
RWM: Does "Beta 1" mean Longhorn Beta 1, or will they be separate?
DB: That's Indigo Beta 1, and that will be in the second half of 2005.
