The new lower-cost HD Tivo has been officially announced. No surprises from the previous "leaked" version, which is good! The biggest "get" to me is the SATA port. According to this article, it's disabled for now, but it should mean extremely easy (and cheap) expansion of the Tivo space. Our very first Tivo was an original 16 hour unit, so I can say with certainty 20 hours will be usable, but tight. However, we've never filled our 40 hour Series 2, so if there's a quick and simple way to (eventually) expand to 40+ HD hours, then we're set.
