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

Yet, at least here in the US, Fujifilm USA did the right thing and replaced the X10 sensor.  I sent them my X10, and got it back less than a week later with a brand new sensor that was, for the most part, free of blooming.

I should point out that the X10 sensor is not the only camera sensor to show blooming.  Go on Flickr and search "Sigma DP1 Merrill".  Browse through the images from that camera and you will see much worse blooming in specular highlights than the X10 ever exhibited.  But if you've ever visited the Sigma forum, you don't get anywhere near the same amount of venom toward Sigma that we see toward Fujifilm.

I also remember my Nikon D70 has a similar blooming issue that while less extreme than the DP1 Merrill or X10, was still there.  Blooming is not unique to the Fuji X10, but sometimes it seems that the absolute hatred of Fujifilm by some Fuji shooters is.

For me, as long as they keep making great performing cameras with class leading IQ, I will continue to buy Fuji cameras.  All new cameras whether it's the 5D3 or D600 have early technical issues.
