Was hoping to see one of those $99 lifetime transfer offers. Maybe next month if they have any left after this sale.
This year is sufficiently different from previous ones(*) such that the past may not be a good guide, but historically TiVo has had their "Summer Breeze" sale with $99 lifetime transfer during the last week (or so) of July for a few years running.
I'm getting a bit nervous about Tivo supporting their DVRs for much longer, hope I am wrong as I have a good amount of lifetime Tivos.
I would be very surprised if TiVo just stopped supporting their DVRs and decided to effectively brick them, and I would also expect minor bug fixes to continue, but if by support you mean substantial new features and capabilities, well, one should never purchase any device based on hopes or promises of future deliverables (since what is actually delivered may not be what you thought it would be), so if the TiVo does what you want today, I would not have a concern about TiVo support, with the expected caveat that (especially) for the cable world, some providers have telegraphed for years, and are now implementing, their moves towards the post linear QAM delivery model. However, if your timing is right, a lifetime CableCARD DVR should still have substantial percentage of its purchases price in resale to those on other cable systems (as long as you don't try to sell such a device when thousands of others are doing the same).
(*) There is, of course, Covid-19, which is impacting the staff of TiVo, and many of its existing and/or potential customers, along with the highly likely impact to the manufacturing location for the devices themselves (China if the FCC label posted during certification is still accurate). And there is the entire newly merged company and management, which may have different ideas as to how to monetize TiVo's assets.
