Megazone has assembled plenty of detailed intel on the forthcoming Series 3 TiVo. He writes:
The unit has two CableCARD slots on the back and it will support Multi-Stream (CableCARD 2.0) or Single-Stream (CableCARD 1.0) cards. If you have multi-stream then you only need one card, but as long as only single stream cards are available you can use two of them. Yes, it supports digital and analog cable, digital ATSC OTA, and analog NTSC OTA. The unit has front panel controls clustered on the right, and a nice display in the middle with a very cool feature – it displays the title of the show(s) tuned at the time, so you always know what it is recording at a glance. The remote ls also sleeker – a slick update of the Series2 peanut with minor changes for HDTV (such as an aspect button). But the big change is that the remote is backlit! TiVo will also be selling an external SATA drive for easy storage expansion, and they have that on display here too.
Mo word on pricing, or a firm release date, but it’s rumored to be mid-to-late ’06. More info and plenty of photos on Zatz Not Funny.
