Aviva Drescher and Luann De Lesseps not coming back to RHONY?

Are only some of last seasons Real Housewives of New York coming back? According to Examiner, Countess LuAnn and Aviva Drescher have not signed on yet. Examiner also reports that the women have been told to “bring it” with the drama this season- “or else.” Apparently the producers are searching for RHONJ “table flipping” drama. What are your thoughts? Is this what you want to see this season?
