There's also a new Olympus due soon that will be weatherproof and have a viewfinder. If it has a new sensor then that could be very tempting. Especially with so many nice and reasonably priced lenses available for micro 4/3.
Feel like the Panasonic GX1 is too little too late.
Need to wait and see now to be honest. I've been spoiled by my 50D and USM lenses and I'm concerned how slow the AF on this might be. I was really hoping for the silent shutter of the X100 as well which this doesn't have.
On the video's the shutter has not been used yet, suspect it makes a noise like a metro door being slammed.
