I remember him saying that he wants to get rid of the alpha tag.
And to repeat myself: not only is S3 announced and known to feature Rockingham and a not yet disclosed car, most of you also don't seem to grasp the concept of Demo, S1, S2 and S3. Those are just content stages totally unrelated to the version number. S1 just means you have access to the S1 content, S2 for S2 content and S3 for S3 content (once it gets released), but no matter what, all content stages including the Demo will use the same LfS version and physics features.
