New devices to be shown in September at Japan's Microsoft Conference 2011?

It looks like Microsoft really is gearing up for a September release date after all. Nanapho.jp spotted the official teaser/sign up page for the annual Microsoft Conference 2011 in Japan. While that's nothing quite unorthodox, they did take note of a particular tile in the banner image on top of the site. You can see that tile enlarged and to your right. Now we don't know about you, but squares arranged in a grid not unlike the Start page we know and love plus text that reads 'New Devices' is enough to make us think some new Mango hardware is set to strut its stuff in Japan. When exactly? The event is penciled in for September 28th and 29th which means we could be looking at a similar time-frame for Microsoft to hold other Mango unveiling events. It's all in the math.
