You are right - we announced last year that we will add a status strip in the first version of RadControls for WinForms, however we did not manage to develop it. We still do not have such control it our package. I have updated the Forum post on the beta to reflect this. I am afraid we do not know when exactly it will be released at this time.
What I can suggest is reviewing the following Forum post - it shows how you can create a custom status bar:http://www.telerik.com/community/forums/thread/b311D-tbcgc.aspx
Feel free to share any other ideas you may have - we will be glad to discuss them here.
