These will likely be similar to the previous Pres and JATP cheapo reissues ... didn't get them as I've got the old versions (same for these two coming ones), but they had cheaper packaging ... not sure how encompassing the booklets are, but while the JATP had a massive one in its original edition (but it still lacks a session-by-session commentary, which I'd have enjoyed!), the Pres a fairly big one wasting lots of space for fancy (and nice) design, the Parker and Brownie box don't have that big booklets, so they might be included again?
Maybe someone here has the JATP or Pres boxes and can chime in?
Just in case, here's a link for the JATP (long gone, it seems):

And the Pres:

Addition: since they're Universal Italy produced (or so it seems), they might be identical, package-wise, to the Universal sets of previous Fantasy boxes (i.e. Chet Baker on Riverside, Sonny Rollins on Prestige, Monk on Riverside etc.).
The only one of those I ever got was the Rollins, which had a minimal booklet with a double page on each album, one side displaying the original front cover, the other listing all infos in the usual Fantasy/OJCCD style. No notes whatsoever.
