Does it have phase detection on the sensor or is it purely a contrast system?

The heart of this question is to see if it is an inevitability that the Nex and Fuji systems will quickly catch up.

It is purely CDAF, no hybrid system. This is why CAF and especially CAF + tracking isn't as good as in a DSLRs.   and also why the mft cameras can't focus older FT lenses, which were designed for PDAF, at the same speed. AF speed s gained both from the body (powerful prcessor) and the lens (lighter elements to move in shorter distances and other design concept  : no helicoid, focus by wire instead of mechanically).
