I agree, 92 series will just get more popular now it was a once service military sidearm. One of the reason's I believe Bill Wilson likes them and started making their own versions.
The Vertec frame does take a little getting used to but for me it works really well, I can really choke up on that grip size. I do believe many shooters will benefit from a vertec grip and I wouldn't poo poo the new grips until I tried one. And I'm sure companies will start making various different grip panels anyway.
The bang for your buck is excellent in this series of pistols! I love the px4 as well but when you start getting into $800 plus it gets to be a hard pill to swallow for one.
My prediction is the 92x will sell like hot cakes and probably attract newer shooters to the platform as well, it is now more conducive to a wider spectrum of people that may have been interested in the 92 but was just physically too big for them to properly handle.
