Just as another data point, TVGOS is still kickin' here in L.A. All eight days. We've never lost the ads. There are usually 2-4 per day plus the "doomsday" notice.
Once the guide and time are gone, I've no intention of keeping my DHGs going. Have no need for a stand-alone tuner and I can't imagine futzing with calculating date/time for the rare occurences when I could use a third and fourth tuner. I LOVE my TiVo.
