I say it's time for Fuji to replace these faulty sensors with new ones that do not "bloom" with blobs. Expensive, yes (for Fuji), but otherwise, I now own a $600 paperweight, which I consider to be way too expensive for me. If firmware cannot provide a fix, this may be the only logical next step from the X10 customer perspective(?).
I can deal with flare, but not this mess. My nightime city shots look like s%^t. And....good luck to anyone who is pre-ordering Fuji's XPro 1.
