Sony Ericsson Xperia X1 - Delayed to December?

There's a lot of excitement around Sony Erocsson's XPeria X1 device which was scheduled to be released soon (around September).

According to EngadgetMobile, this will be delayed to the end of 2008 or even January 2009.

Looks like it's a new fashion to delay things (Bold, Nuvifone, Android) up.

(Maybe they are replacing Windows Mobile with the Android?)
