Not a typo!!
Just found the details on the German Walther site. You can view the English version at www.carl-walther.de/englisch/defense
In short, it is a new pocket pistol with "new technologies" in a world famous classic design. . .will be in high polished blue only and similar size to PPK/S.
According the the tech data, the /E will be slightly heavier and larger than a PPK/S. I just e mailed Walther in Germany asking where it will be manufactured and whether or not it will be exported to the U.S. The picture looks very nice on the detailed view at the site.
