Well with 0 hour getting closer more news is leaking down the BB spoiler pike. If you look at these two pictures, BB6 and BB7 house, the memory wall is shown. In looking at the BB7 Memory wall it appears 9 frames are shown, if you add only 3 more to it, the walll would not appear balanced. At least not the way it looked in that picture. Hence, it would seem that maybe just maybe two more HG's will be joining the 12 already slated to go into the house. The only questions are who and how would these 2 be selected.
