I love my X-T1 and X100s. I think you'll be incredibly happy with the X-T1, especially with a 56mm ƒ/1.2. I dumped my 5D Mark II for it, and haven't had any regrets. My Flickr: https://www.flickr.com/photos/aaronbrethorst
You know, there's something about these damn Fujifilm cameras. My Finepix F100fd knocked out perfectly exposed shots, with fantastic color and skin-tones all day.
Even my GF1 can't seem to manage the same thing, though my D70 does pretty good.
The GF1 was good but it was a very early generation m43, any recent one from Panasonic or Olympus gives much better performance overall and will easily outperform your D70 (I moved from GF1 to E-M10 a few months ago).
