This does look interesting to me too.
My interest in Micro-FourThirds was renewed when I picked up a used E-PL1 a few months ago as a vehicle for "entertaining lenses", and because I still have the glorious Olympus ZD 11-22/2.8-3.5 lens (my only remaining zoom, and my favorite zoom lens of all time) and the E-1 SLR (my favorite DSLR of all the ones I've had).
Since using the E-PL1 as a special purpose lens carrier, I've been thinking about where I want to go with this format. I handled the E-P5 recently and found it a tremendously improved camera over the E-P2 and much more likable to my hands than the E-M5. This new GX7 might edge it out, tho, as ergonomically it looks like a down-sized L1, a camera that I am still extremely fond of. It has the sensor cleaning, IBIS, and short mount for my "special" lenses, as well as could work with both my 11-22 and 35 Macro (my last dedicated FT lenses). The dual control dial system looks a lot like the E-1's too, pretty slick if they feel good.
I look forward to seeing one in person, and then I look forward to seeing the files when Lightroom supports processing the raw files.
