TiVo With Full HD Support Coming?

Word is going around that some interesting improvements are coming to TiVo. While it’s still unconfirmed, it seems that there are full HD menus on the horizon, improved search functionality, and also the phasing out of Series 2 hardware. It’s possible that the old user interface and operating system will be replaced by a full HD version, and will be available first on Series 3 hardware. Are you currently satisfied with your TiVo setup, or are you unhappy that the company has stopped making improvements on the current software sometime during the middle of last year?
