The f2.8 zooms become the aps-c equivalent of f/1.8 zooms in FOV/DOF

New FF Lens'. What would you like to see as the kit lens? Olympus has a 12-60mm f2.8 it is an excellent lens and was my fav walk around lens. I would choose something in that range.

Personally I don't see any reason to use f2.8 zooms on FF. The advantage of FF is wide and DOF, so why would you not use fast primes to maximize the DOF advantage?

You do still gain quite a bit using f/2.8 zooms. At 24-70 2.8 is about what a 16-50 f/1.8 would be on aps-c, if such a zoom could exist. You basically gain a little over a stop in DOF control with the f/2.8 zooms on FF.

The f/4 zooms from Canon (and now Nikon) would give you just about the exact equivalent of the f/2.8 zooms on aps-c.
