If it can do reliable 9+ fps tracking with 90-20/2.8, it competes with $6,700 1Dx (+ $13K 200-400/4 1.4 Extender to replace that $6,000 90-250).

If it can only do 4 fps or not reliable, it competes with $1,500 6D or even cheaper 70D/D7100 (and loses to the latter for the sports, and there are other cameras like E-M5 which are perfectly good if you don't need sports).

This also depends on the AF motor inside the 90-250mm, 7-14mm, and the 35-100. None focus as fast as the 14-35mm f2 SWD.

"Olympus's exclusive SWD-driven ultra-fast AF system, a mechanically interlocked manual focusing mechanism"

The 12-50mm SWD and 50-200mm SWD will also benefit fully from camera body AF upgrades.  The 12-60mm and 50-200mm have always been a very sweet setup in terms of performance, size and cost. They will be a good pair of lenses for m4/3 users who are willing to carry such "large" lenses.

The SHG lenses will continue to be rare exotics.
