It will get updated, Franco was busy with his personal life as he became a Father. Really not easy to cope up with everything! If you look at other devices, all of them were not updated. Updates will come when he starts developing kernels again.I'm quoting you but this advice is for everyone one that wants to know about an update:
before asking, check the kernel source github. It's on the OP. If you check it, you're gonna see that latest commit to franco's kernel was in September. So it's doesn't seem likely this will get an update, at least not by franco (last commit was from other member, I think it's a cherry pick or merge, not sure).
But, seeing that it didn't get any update in months (a lot of things happened since then: new touch drivers, android q, miui 11 on android q) we can assume that it won't get any update anymore
that way we don't ask for ETA and still can get some info
