I agree with John. The LX7 and X20 would be an either/or for me, with different strengths, weaknesses, tradeoffs (including price). But I tend to get more excited about the high zoot cameras like the X100s or RX1 or Coolpix A, when those are on the horizon. The LX7 came down in price in that lull between the new releases in the summer / fall and the next batch in the spring. And it was too good a deal to pass up for a camera I already knew I loved. But if the RX1 had been on my radar then, or if I was thinking about it now with the X100s and Coolpix A about to hit the streets, I'd probably be saving my money for one of those. As is, I'm selling off some m43 gear that's not getting enough use.
