That is entirely your own decision. My personal standpoint is that, given the release and all info that was mentioned around it is enough of a hint that good things are coming. MAXON is also more open since in the very release there are mentions of "first incarnation", "first iteration".etc. At this point I simply don't know if MAXON will decide to provide some additional information and I can only repeat or clarify what is already known.
I am also intriged by this one, I don't see the benefit at the first sight, it seems to be a pure under the hood thing.
As said on MAXON website, In R19 you won't notice much from user standpoint, however the first part of new modelling kernel is implemented, and even though it may not seem like it, it is huge undertaking. Later, with following releases you will see real tangible results for tools that you use daily. To create top notch tools, you have to have top quality core "machine" to handle that all. Last thing MAXON wants is to slap new tools and workflows on old tech. As an example, new poly reduction is done around new kernel and you will see it is very fast and modern.
