Thanks for bringing this to our attention. Currently Smoke for Mac OS X should only be available on autodesk.com as the pre-release trial, linked here, which is also referenced when you select the product in the Education Community. The drop-down that contains the 2012 version appears to be a test that should not be showng up on the live site.
I apologize as I’m unable to comment on upcoming product release dates or the features that may or may not be included in future products or product versions.
