Following Sony New Zealand, Sony Japan today updated its dedicated Vaio website with a mysterious announcement. If you click here [JP], you can see a woman getting out a small UMPC-like object out of her hand bag.

Clicking on the flash animation takes you to another page [JP] where you can sign up for an email newsletter [JP] (provided you can read Japanese and have a Sony Shop ID).

The announcement is a little more concrete than the one that was on Sony New Zealand’s site a few days ago (they took it off) but it’s still unclear what the new mobile PC is (provided Sony is hyping the same piece of hardware in these countries).
