With rare exceptions, I think that time for invites is drawing to a close. Some schools will not get back to you until late Spring, a few may never get back to you (rude, I know) to say that you were not among the applicants selected for admission. At this point, be thankful for the offers you do have, be glad that you got offers well before Mardi Gras (next Tuesday), and start the process of making a decision about matriculation. Good luck!
