My prediction: hell yes.

Not only do Mac gamers have the official announcement that the Starcraft II beta will be warping in on OS X on Monday or Tuesday, but Valve has announced they’re releasing the brand-new Steam UI on Monday. This is a good reason for Apple-based gamers to be excited as Valve slated the Mac Steam UI for an April release.

You do the math: new Steam UI + April = good chance of the OS X interface being released.
