I suspect there may eventually be an update since Tivo has to at least pretend to support the core legacy streaming apps on the Bolt/Edge, but I wouldn't expect it anytime soon. Things like this have a tendency to randomly appear a year later. As for the one box solution, the Bolt will never be that unless you are content with their limited app selection, older app versions, and limited 4K/HDR support. Tivo's future seems to be in streaming sticks in the android ecosystem and not their older DVR's, so support for these will likely deteriorate even more in the future.
As for the overheating, having the Bolt sit directly on top of a USB powered 120mm fan has worked well for me. Keeps cool air moving under it.
