Quote - Well, marketing is a huge factor also (but yeah DAZ does very well there too).

It is, but IMHO not as much as one may think. A marketed product that doesn't live up to the hype tends to flop real hard. (Example? Apple says nothing about upcoing products until they're released. Microsoft hypes the unholy crap out of theirs, with mixed results. Windows 7 managed to make it, while Vista, Kin, Zune, etc did not.)
