My prediction is based on Carol Ann Susi, known to us as Debbie Wolowitz, Howard's mother and the the wonderfully funny actress who played her and died year before last. It would really be a shame if producers didn't make a tribute to her, someone unseen that contributed so much laughter to the show.
My prediction then is a baby girl. Her name could be any of the the above names. Obviously the child will be a Wolowitz, but any name such as Carol, Ann, Debbie or fudging it to be even Susie. However Deborah, as many know, was the only judge, who was a woman, in the Bible. Her story is told in Judges and the name is perfect for both the Jewish and Christians. It makes sense that their baby would be named after her.
The name could also be a bit humorous too, calling her "Little Debbie". That would be perfect!
