The most in-demand custom knife maker collaborated with a reliable knife manufacturer(who literally has no complaints regarding QC, fit and finish, and customer service) to bring to everyone, for all intents and purposes, a mass produced version of his most popular knife(search around for XM-18).
For the price, I'd consider it well worth buying. I did gripe about the outdated(to me) S30V and 154CM in a lot of the ZT line, and having Vanax35 and Elmax available is a welcome upgrade. It looks somewhat similar in size and shape to the ZT 0300 series, but there are a lot of subtle differences that make them both unique and perform differently.
Custom collaborations have always seemed to be pretty good for me(BM 755 Sibert, Spyderco Gayle Bradley), and I've always drooled for an XM-18, but the price tag put me off. Given that the price of this new knife is more or less the same as a ZT 0300 series, I see no reason not to go for this one.
