Well I did say that my opinion wasn't balanced, although every production house I've been in lately have all swapped over to Vray so that must mean something, one of them I know has trialed every available renderer for Maya and has now adopted Vray. Then the next company I think I'm going to be working for next year has recently done the conversion to Vray, of course it may be a fad. I don't even think of it as turning away from Mental ray, it's just an alternative that is worth investigating isn't it?.
