WILLCOM releases successor model preview site "x - w.jp" of W - ZERO 3 released this summer

WILLCOM released a preview site "x - w.jp" that W - ZERO 3 successor models equipped with Windows Mobile 6 will be released this summer.

Apparently the release of successor models of W - ZERO 3 seems to be close.

Details are as follows.
WILLCOM | x-w.jp

Apart from OS and release time, details are not yet clear, but "X" seems to be a keyword this time.

Is not it really the name "X - W" as it is ...?

I tried searching with the domain name "x-w.jp" as a test, and it became clear that it was the domain which was acquired on April 2. It is only recently.
