I infamously made this same sort of prediction when 4e was announced.
Please trust me when I say there is no benefit to this sort of declaration. If you're right, it will be meaningless. If you're wrong, it will be repeated for years.
While I don't predict 5e2024 will fail, it's possible it will fail. It is possible a meaningfully large number of people who previously bought 5e2014 won't buy 5e2024, and that it doesn't gain enough traction with new players.
So consider this a warning from the future you - leave room for doubt.
Oh, I ALWAYS leave room for doubt, but keep in mind - I have successfully predicted the sales of every D&D product since 1993. I'm not claiming 100% accuracy, of course, but close enough to always turn a decent profit. Sure, there's been a few books that I sell out of early (or late) and some unfathomable oddities (like how my store hasn't turned over even a single copy of Curse of Strahd Revamped in the past year - who could accurately predict THAT!?) But generally? My track record is very good.
My gut says that D&D2024 will not quite reach the highs of 5e (at least, not in Print Sales, and certainly not in its shocking sustained growth) but it WILL do great out the gate (so did 4e) and everything else depends on exactly how good it is, which I think people are going to be pleasantly surprised about, but that's definitely more nebulous a prediction. I mean, I predicted the SALES of Spelljammer successfully, but I really expected it to be better, for example. Go figure.
But I take your well-meant suggestion. I'm always happy to admit when I'm wrong. We'll have to see.
