Yeah, with the 24 it would be a question of full coverage. I suppose it might just fit - there's enough space around the 18mm frame lines in the unmagnified view. But then with the 10-24, I don't see how it could. And with the zoom(s) it would be more a question of whether the frame lines would constantly adjust as the lens zooms in and out. I know the OVF is more critical for some uses than others, but I just about always PREFER it to the EVF and if it doesn't work with some lenses, that's a strike against them for me. As I'm using both the X-Pro and m43 systems (and already have a nearly full set of m43 lenses), there are going to have to be compelling reasons to go with the new Fuji lenses. The 10-24 is almost a given, since its close to the coverage of the 7-14 Panasonic and it would fit with my travel kit needs/wants perfectly (one body with a superzoom, one with a UWA, and a couple of fast primes in the bag). But for any of the others, if they don't work with the OVF, its a pretty serious strike against them, since the OVF is one of the HUGE charms of this camera for me.
The evolution of this system, both in terms of lenses and future bodies, will be very interesting to watch. I'm quite sure its in my bag for the long haul, but whether its as a primary part of the system or just as a niche, change of pace, type of thing is far from determined in my mind.
