Ayumi Hamasaki appears on the website of the new D-Dock and D-Snap cameras:

She's wearing a blue dress in which she seems to be flying (lol). Her long hair suggests that the CM has been recorded before her haircut, or that she's simply using extensions.
So there are new CMs coming up, with possibly a new song.
