Fuji doesn't have nearly the lens lineup to make it even close to worth my while to completely switch. However, if things progress well there, then in a few years, who knows.
Right now, I am not even sure how long I'll keep the X-E1....I'm going to give it a run for times I need really high ISO performance or shallower DOF than I can easily get from m4/3, though those aren't really key areas for me, so it may end up sitting on a shelf for most of the time.
Part of the impetus (besides the above) is to have a body to do further lens reviews and such from....now I can review all the Fuji gear too, without having to rent bodies all the time.
I do think I may grab the X-E1 in situations where I'd only want to grab one lens, especially if I'm shooting in dark situations where I need the shutter speed vs IBIS. The Leica 25/1.4 is the sharper lens in my early testing, so I'm not gaining anything there, though the rendering of the 35/1.4 and the bokeh is quite beautiful, so we'll see.
I think this makes more sense than the X100s for me. If it doesn't work out, I'll sell it and move on. EVF is nice, though...
It is a sharp looking camera, though:
