Ahead of a March 2 event and TiVo HDs suddenly going extinct, two listings for a TiVo Premiere HD and Premiere XL HD have popped up in Best Buy's system.

The Premiere XL is THX certified and records up to 150 hours of HD content. It's $500. The regular Premiere records a third as much, 45 hours of HD content, and it's $300. They're expected to land at Best Buy on March 27. Of course, prices and dates and recording capacities we expect will be by far the least interesting aspect of these things. We hope. [Engadget]
