I expect the chances of there being a 'last' version are about zero. Gibson won't make money and if they cared about any response/backlash it would have been indicated in the official announcement. They'll just retain the IP/copy-write/patents (if any) and sue people that make something similar but won't do anything with the actual content itself. Those Cakewalk music babies have been drop-kicked into the ocean because they don't please the Gibson shareholders.
However, I'd think the chances of the chaps in the bakery doing something helpful outside of the constraints of their Gibson overlords are pretty good, even if its just a conversion tool for projects. Perhaps as an import option when they get wherever they end up :)
I obviously have no clue what's really going on and like everyone else am just speculating.
