This is great news! Vray for C4D is at the moment the fastest render engine in C4D, but its development process is super slow.
And it does not support deform motion blur & object motion blur (well.. object motion blur works - some how, but it has lots of bugs or what they say: "features".
I really want to see Corona for C4D with object, camera & deform motion blur features, at least it should be possible
to create full motion blur support because Mental ray for C4D already has it (but it is slow rendering engine), and Vray will add it to the next version (but, i guess we will see it after couple of years :).
