I think I over thought this and have ended up making a rather expensive misstep. Like a lot of us I have voiced my dissatisfaction with the AF on the NEX. Since I am primarily a user of legacy lenses I haven't really been feeling the need to move to a different system. I picked up an X10 to have as a fun go anywhere camera. My 5n is small but the Rokkors on it can be a big large and in the case of my 24/2.8 quite heavy. There are some times when I need or want AF and I did the whole Sigma 30 route but it didn't really end up something I used a lot. I like the lens and think it's a terrific bargain but it got very little use. To that end I bought a Panasonic G3 and Sigma 19 and 30. The G3 was cheap at $249 NEW for the body and the lenses were less than $300 for the set (used). I had heard that the Sigmas AF very quickly on m43 and it seemed like a nice solution. The G3 and lenses are set to arrive today and I realize that the X10 is doing everything I wanted the G3 for and doing it pretty well. It has fast AF, the images look great, I can do macros, the lens is really quite good and at 2.0-2.8 it's fast enough for most of what I need it for. In RAW I think the X10 produces images that aren't that far off of 1st generation m43 images. Add to that the fact that the X10 is small and feels great in the hand and I'm here wondering what the heck I need the G3 for. I'm sure is a fine camera but I just don't see that I need it. I had even thought the G3 would be a better platform for my long telephotos but I am even rethinking that idea. I think I might just return the G3 and lenses without even opening the boxes. It'll cost me about $10 in return postage but I guess I can consider that my stupidity tax.
