Will Arnold support Blender ?
We have no immediate plans for an official Arnold to Blender plugin.
No. Arnold is part of Autodesk, it has nothing to do with agreements.
We have to balance time, resources, and priorities, and we can't do everything we want to do.
There is an unofficial plugin being developed
there open source project.

anyway, i think it has something with blender users. ask a blender user to use anrold--> the answer of 99.9% of users will be "why paying for arnold, if i can have cyclesX for free?"
Except for path tracer SSS, Cycles can do almost what Arnold do but with much faster render time. Why do you need Arnold for Blender ?
I am a hobbyist 3d enthusiast and my main interest in using Arnold as a renderer is for it's powerful NPR features, (OSL/ edge detection, etc. etc.). Blender has a new exclusively NPR renderer called MALT but it is still in an infant state.
In my opinion, Arnold NPR features are the best I have encountered so far which is why I would have loved to have found an official Blender integration. The unofficial integrations i've found in Github are either still under development/buggy or abandoned.
there is new version
