I'd argue that Fuji had sucess with the X100 because they held back from exploiting there first to market status and priced it at a level that made it affordable to the wider market. They could probabley have sold it for £1500 at launch and it would have done decent business but I'm guessing overall profits and interest generated would have been less.
Sony's tactics with the RX1 seem more similar to Leica's with the X1 to me, looking to exploit a first to market advanatge by charging a prenium and so arguebley squardering there position.
An RX1 with either a better speced body or a lower price could potentially have been a great sucess for Sony IMHO.
The chatter about the X100 was that it was too expensive at £1,000, I didn't see anyone say that they would pay £1,500 for it. Fuji would find it very difficult for a number of reasons to price a fixed lens crop at Leica prices. The body looks pretty well speced and the full frame Sony sensors are offering excellent results and with Zeiss designs you couldn't ask for a much better marriage.
