Speculating on a release date is merely speculation, so I wouldn't read anything into that. Perhaps you can contact Solid Iris for their take, and see if your qualifications would allow you to be included in their testing (if you really want to test and not just try).
VRay is very different from Maxwell, and you should probably study up a bit more before making such generalizations...
Tech, I'm sure you can tell I wasn't intending Justiin to speculate on release dates but I sensed he's getting a tad impatient for an alternative to RenderZone to be available within FormZ so I wanted to let him know it's unlikely in the coming weeks.
And spot on that V-Ray is nothing like Maxwell but somehow there's a common perception out there that there are GPU renderers that the answer to all our prayers and then there's the boring old slow CPU based ones. And as we both know that's just baloney!
