Personally, I'd much rather they did NOT lose the legacy cabs. I have hundreds of presets that use them, and I am not going to go through and tweak all those just to get sounds back. They work just fine for me, I'm very happy with the sounds I get, I play music with them rather than spending hours tweaking sounds that nobody will ever notice in a mix, but would still like to have the Dynacabs that we now have to have a play around with them occasionally.
Maybe I'm turning into a stick-in-the-mud in my old age?
