Is the new E-M1 just an updated E-M5 with PDAF sensor?

The latest E-M1 specs leaked by photorumors suggests that the upcoming High End OMD may be a slightly updated E-M5 with PDAF sensor. It has the E-P5 specs, VF-4 viewfinder (integrated) and OMD design. The major news is the on sensor PDAF which will add 100% support on Four Thirds lenses. Will that be enough to compete in the $1500 market? Doubt it…
