UPDATE: According to Leica US, the X1 camera will be on time for the scheduled January 2010 delivery. This rumor is busted for now.
Arlingtoncamera just confirmed the news to LR: their Leica rep has told them that the Leica X1 will be delayed until February, 2010.
I see two reasons for that delay: either Leica wants to concentrate on M9 production in order to satisfy the current demand (see this post) or the latest X1 review at dpreview was not up to par with Leica’s expectations and they are working on few final tweaks.
