I don't think Yaesu has any more of a monopoly on System Confusion that iCOM does on D*Start. I could be wrong.
Around here, at least, all of the buzz (yeah, it's a pun, get over it, I do that once in a while!) has been over System Fusion and DMR. No one is talking about D-Star, P25, or NXDN. Right now I would say that Yaseu has the majority of the mind share at this moment. Of course, that could change if a new player emerged.
