Price guestimates of the 35-100X?

On the basis that it's probably an f2.8 lens, what do people think it's likely to retail for?

A Canon 70-200L f2.8 starts from $1400 by the looks of it. Are we likely to see something similar ie. the first $1000+ mFT lens?

Don't have much experience myself with fast glass, so be interested in opinions.

Weighing up whether to wait and see or plump for the 45-175 - no point waiting if the 35-100 is completely unattainable for me.
