Yes, saw the official spec too.
I always try my best to support the camera brand I like
(so long as Emjay don't try to 'kotok' me for my love of Pentax) 
1. Smaller and more streamlined (w/o lens or with the 40XS)
2. Peaking for MF not better?
Prime M processor that can support the faster video rates already means its faster
Easier and faster with MF lenses - peaking; zoom window without the current shutter 'double drop' on the K5
WYSIWYG AF and MF.
Don't know what else (I hope no AA filter??)
So can't say its not better.
For the advantage of using MF lenses, I'd get one.
3. Cheaper than the K5 for the same sensor (at least the same performance)
4. I had lots of fun using GF1 w/o viewfinder; so do lots of ppl w/o one on NEX and m4/3 so it can work, esp with nice small native lenses with
AF (not all positive w/o one of course)
5. ~so so~ with the design (not great, but I do like the black knobbed one)
6. Battery life remains to be seen. No big deal with my G3 with has an even smaller battery capacity.
Not really a big issue too since everyone carries spares (even for a DSLR) and 3rd party ones are cheap.
In fact I don't even need to buy new ones since I still using the ones from K7/K5.
Also don't forget that its a cheaper alternative for those stepping up from a K10, K20, K7, Kx, Kr.
So Fact; Not Fan
