Anyone left m43 for Sony APSC?

Hi,

I am quite happy with my GX7 but also looking for some bigger sensors cameras like the new A6300.

My questions are the following:

1) Would be worth the change from the m4/3 16mp sensor to the APSC 24mp? Is the cropping capability considerably higher?

2) Is there any good all around lens like the 14-140mk2 for Sony?

3) Did you miss the touch screen of m43?

4) How is the interface of the A6300?

5) Are the Sony lenses considerably more expensive? Is it true that the lenses for this system are not many?

Please feel free to share your impressions from such a change.

Thx!
