Why not a Fuji X10s?
... with the improved Orb free sensor, faster focusing (+other improvements found in X20) but with the same stellar jpg performance ... instead they intro the X20 which appears to be somewhat underwhelming in the IQ dept compared to the claims Fuji has made ... and quite overpriced (at least for now) I guess the X10's that were sent in for the sensor replacements are already technically an X10s. I sold mine to buy the X20 (due to the hype of improvements) and ended up trying the Canon G15 and am now considering going back to the 10 ($400ish vs $600ish for the X20)
I agree why not just call the Fuji X20 the Fuji X10S, it follows with the X100 and X100S. But with that new Xtrans sensor tech, I guess they wanted people to know that this is something really new.
