You aren't alone, but you also probably aren't part of any sort of majority. There will be plenty of players out there that will look at 2024E and see little difference from what they currently have, except for some edits to features that they could easily port to their 2014E game (re-written Great Weapon Master feat, re-written stealth and Hidden rules etc.) and just choose to snag those few things and incorporate them into their own game, rather than buy new books. WotC most likely knows and understands this, and is fine with it. All along they've known that not all players will pick up all the books.
But I do not believe they are doing these new books with the expressed purpose to "re-sell" to current players and get more of their money... they are doing it to get new versions of their books on their shelves that new players coming in will have as a baseline D&D that the designers are happier with. They've been doing this exact thing this entire time by incorporating errata in every new printing (and have never once implied they expected current players to "re-buy" the books now that they had these updates)... and the same could be said about 2024E. WotC will not care if a handful of players choose to just stick with 2014E... just like they said upon the publishing of 2014 5E that they were completely fine if players continued to play previous editions of D&D and not upgrade to 5E.
WotC doesn't need all our money, so they don't really care if some of us do not buy the new 2024E game. All they really are happy about (and it has been this way since 5E's release) is that we are playing some type of D&D. Because that is the best advertising for them. Happily playing any version of D&D (or indeed ANY RPG) is the best way to inspire other players to start playing as well. And no one who doesn't play the game knows what version any of us are playing, all they know is that we are playing 'D&D'... so what we ARE playing doesn't matter. And thus when those people make the choice to jump into the pool, they will pick up the current version of the books that WotC wants to be out there because it's the easiest and most talked about version available to them.
Which in this particular case will have a big change that WotC is looking for at this moment in history, which is the word 'Race' removed from its gaming vocabulary and replaced with 'Species'... done in an effort to try and distance potential negatives and miscommunications of meaning with those new players. Personally, I think even if they didn't revise the game itself fully for 2024... at barest minimum they were going to print a new version of the 2014E rules with indeed that word switch. That was happening regardless. So at that point they figured if they were going to make that big of an obvious change, they might as well make big changes to other issues of the game at the same time.
But they know perfectly well that some players won't embrace that particular change (and some will out-and-out rail against it)... so they aren't expecting all of us to follow along and buy the new books. They'd like it if we did... mainly because those of us who have been whining about the same crap rules for the past 9 years might finally get our complaints taken care of and we'll finally just shut up about them... but if not, so be it. Those who don't move on to the newer books can stick with what makes them happy and/or irritated... and all the new players can start their D&D career from the place WotC would like them to start from.
