Yep, Bix was last year. As for box-sets, RCA already put out a complete Glenn Miller set, and I doubt they have the economic nerve to tackle Fats' considerable output... how well did the Keepnews-produced volumes sell? It seems--I say seems because it's mostly based on my anecdotal observations--that the major companies are just a bit more wary of putting out complete, large, and/or comprehensive sets these days than they were a few years ago.
I do hope that the Hawk gets his due. Basie, I'm sure, will not be overlooked.
