would Fuji do the same stuff up again with the X20 (orbs &QC)

Expect this forum and others online to analyze every specular highlight with 1:1 crops.  If each and every one is not a perfect ten point star without the slightest hint of sensor blooming expect users to throw Fuji, not under the bus, but under the road the bus is driving on.  

Since the X20 has a completely new sensor with the same X-Trans technology found in the excellent X-Pro1 and X-E1, I don't expect any issues re: blooming.

I've owned 2 X10s and have never experienced any QC issues whatsoever. On the contrary, the X10  is one of the best built, most robust compacts I've ever owned, which is exactly why I will buy an X20 straight away without waiting for any reviews at all.
