Am I crazy? Considering selling my RX100 and getting a Canon G15 or Panasonic LX7.

Not to mention missing many, many shots because of the sloowwww AF times compared to the LX7. Nobody buys a G1X to take action shots! I'm sure you can hold off buying until the reviews of the Fuji X20 come out to see if all the claims of great IQ, and AF times are confirmed. That would be your best solution "IF" all the marketing claims are confirmed. If they are confirmed, the prices of the G1X should drop even more drastically then they already have, for good reason. The G1X is definitely a niche camera, great low light images and lens, but that's about it.
