"Only You" is MM's next single. I don't know what style it is, but judging from the outfit, it might be a ballad. There are other blog posts with images, too. As for what I want next in a MM single... well, a ballad would be nice. I wouldn't mind another cool type song, either.

I don't think the song is going to be Maji Desu Ka Ska style, judging by the outfits. But outfits have steered us wrong before. Remember the Aruiteru outfits? Those were about as least feel-good-ballad-y I could think. They seemed more like they were made for the b-side (Morning Curry).
