I don't think there's any coming back from an announcement of this magnitude like the PS3/PS Vita store shutdown attempt several years ago. This is something that Sony would have spent years building around the PS6. No longer manufacturing discs to prepare for the next-gen console would've been decided early in R&D. While it's currently unclear if they'll at least sell a disc drive separately for BC, it is clear that this was Sony's move to bridge the gap between console and their upcoming handheld. Their own version of Play Anywhere.
Even if by some miracle they backtracked, that's a lot of goodwill lost with the hardcore gaming crowd. Casual market won't bat an eye, but it's still a big "FU" to the gamers that have been with PlayStation for decades who were still buying physical, and always were going to.
