I always like to investigate these analyst firms. In nearly every case, it's just some guy. Usually their predictions are about as enlightening as a horoscope.
In this case, the person behind DMC Intelligence is David M. Cole, and he's got some contractors who work with him under inflated titles to make the company seem more reputable. He's been doing this since 1994, basically since he graduated college. I always assume people like this have trust funds, or else they did other work until the prognostication business became enough to sustain him.
Here's one such report, which makes the vague guess that Nintendo will come out on top and either Sony or Microsoft will struggle in third place because "there isn't room for more than two major console systems." There's no justification for that assertion at the link; presumably you need to pay for the report.
