Nobody I game with has said they are getting the new books.
I play in 2 weekly groups and one biweekly group. All of us at some point played 5e. One weekly group is using OSE now (I'm the DM), the biweekly group is now playing Dragonbane (really fun - you should check it out if you haven't yet played it!), and one weekly game is still playing 5e. Some overlap of players between groups, but 14 total players. While a small sample size, it's fairly representative across a 30 year age range, with some having played multiple editions over several decades, and a few that have only played 5e. Three of them have successfully funded and published RPG Kickstarter campaigns, and another has a playtest credit in XGTE (along with 1000 other people) which is to say that as a whole they are hardcore gamers.
I recently polled the 5e group if they were aware that new books were coming out, and if anyone was considering switching the game to use the new rules. Of the 5 other players, one had heard something about it and the rest hadn't. Our campaigns usually last over a year and then someone else takes the DM chair. Next month we're starting a new campaign using 5e which will probably take us into 2026 before we revisit a rules change.
I've been holding out hope for some 50th anniversary Greyhawk love from WotC, and my OSE game is set in Greyhawk, so I probably will get the new DMG just for the Greyhawk content and map.
It seems like this new edition isn't something that people have been clamoring for, but rather an attempt to reset the marketplace so that people will migrate to WotC's proprietary VTT where they can be transformed from game owners to game subscribers, just like every other company trying to turn us all into digital serfs.
