1. ...there is a four tuner model available. 2. ...the second core is activated/minimal reports of HD menu lag. 3. ...the menus other than the main menu and find programs are in HD 4. ...I can upgrade my existing lifetime sub (now 9 yrs old). Well, if I can get the first three, I'll pull the trigger. I actually played around with one in Best Buy (no cablecard inserted), and didn't find the HD menu to be slow. But other than the Main Menu and Find Programs (and the disc usage meter), at this point, I don't see a compelling reason to upgrade.
