Zen Pinball developer Zen Studios is being pretty mysterious today.
Zen Studios has produced a range of popular pinball simulations including the Zen Pinball, Pinball FX, Marvel Pinball and Star Wars Pinball series.
Today it released this teaser image via Twitter:

The buzz around the tease has largely pointed towards some sort of Valve-themed pinball game, perhaps with tables based on Half-life, Portal, Counter-strike, Team Fortress 2 and Dota.
I have to say, though, I think it's significantly more likely that the tease indicates existing Zen Studios games may be coming to Steam; the colouring of the image in particular looks very Steam-like.
Still, Zen Studios has already released a number of titles and content packs on Steam. There's certainly hope for something more exciting than ports - although for some pinball fans, that will be exciting enough.
