I recommend you to check more videos at youtube, because the one on Phoronix doesn't show true gameplay at all:

And it shows.
Besides some obvious bugs they need to squash (which you can read in their Linux bug reporting thread on that forum), when I fired up Wargame:EE it felt like I had just fired up a new game in a typical Windows gaming PC; the game ran without any complaints and was just smooth everywhere and I haven't seen any visual glitches.
I guess what I mean to say is it actually feels native rather than some half-assed port.
I do hope you are right as that sounds like the optimal scenario. Can you link me to where CD Projekt showed interest in supporting Linux? Introducing Linux support at the same time as launching The Witcher 3 (its launch hopefully including a Linux client) sounds great but what about Cyberpunk 2077 which is another title they are currently developing? What about The Witcher and The Witcher 2? GOG did not launch support for Mac OS with any new, major unreleased games either so it worries me.

Not the link I was trying to find but it work, for can't remember where the one I was looking for was, so was mostly just using google magic to find it. =p
