I am also awaiting the zoom since it should have image stabilization. I would have preferred the three primes, but they saw fit to not include image stabilization in the body. Not sure why, the body is certainly big enough to hold it. I was veryd disappointed it did not have the IBIS which is almost a dealbreaker for me. If the zooms have stabilization, then I'll relook and possibly buy.
I'd have been shocked if they'd included IS. Consumer gimmick and an extra expense. Zoom lenses is where it belongs, not on a body primarily used with fast zooms.
Off the top of my head I can't think of any high end bodies that have in body IS. Pro Canon's, Nikon's, medium format and Leica all manage without it. Useful on longer, slower, zoom lenses but I don't need it on a camera like this. This isn't a P&S.
