It may not feel like it since some of the recent releases from the band are things that many of us aren't interested in, but in recent years there has been a steady flow of stuff coming:
5/17/24: Animals Atmos blu-ray
4/19/24: Dark Side of the Moon picture disc
12/8/23: Atom Heart Mother CD/blu-ray
10/13/23: Dark Side of the Moon Atmos blu-ray
7/28/23: Wet Dream CD reissue (with blu-ray following shortly after)
3/24/23: Dark Side of the Moon 50th anniversary box
3/24/23: Dark Side of the Moon live at Wembley '74
10/21/22: "Hey Hey Rise Up" single
9/16/22: Animals 5.1 blu-ray (plus box set shortly after)
4/29/22: A Saucerful of Secrets mono LP (general release following an RSD exclusive release a few years prior)
10/29/21: A Momentary Lapse of Reason box set
4/30/21: Live at Knebworth 1990
11/20/20: Delicate Sound of Thunder CD/Vinyl/Video
12/13/19: The Later Years box set
That's just in the last five years, and I may have even missed a couple of things. So it's not like there's any reluctance on the part of the band to reissue the old catalog. However, with Gilmour's forthcoming album looming, I doubt we'll see any old Floyd albums getting any sort of reissue until he's done with the promotional cycle for it. Wish You Were Here was a September '75 release. So we probably won't see the 50th anniversary reissue of that come until late next year. Will they fit something in between that and DG's album? Possibly. Given the rate of releases above, it's not outside the realm of possibility.
