Will these be coming out as a mega-set?

Seth,

There has been no indication of such as of now.

I think there was already a compilation of some of the sets...the first six or so IIRC.

Yes. It was just a bundle of the first 6 sets, not a specially-made box:

I'll have to check my local Costco for some of the later years.

Okay, here we go. In addition to the individual sets, which will remain in print, the entire run of Three Stooges shorts is now going to be officially collected into one 20-disc set including a 3-disc bonus set of solo shorts (which, according to the preliminary description below, will eventually be released separately too):

I'm going to want to get that bonus stuff--for moment there I was worried that it would be all that depressing 60's material.

per Linda's posting above of "The Ultimate Collection" box, the 3 disc bonus set "Rare Treasures"
(featuring the 2 movies and the solo shorts) eventually came out sometime last year, currently available
at 43% off, operators are standing by (yay), woo woo woo woo woo:
