Ultimately, I really do think it will be a mixed environment like you say (or a different paradigm entirely). There are a lot of NUI proponents who gas up their work in speech or touch (and touch related) interfaces. I do agree that they will be used pretty widely (maybe not so much speech...) but all of these technologies remain stop gaps in the sense that a mouse was a stop gap solution. They are great technologies that are great stepping stones to something truly natural* that encompasses more than one method of interaction * I don't necessarily think "natural" is necessary in the future, but that seems to be what a lot of folks strive for.
