I think Lauren (Mimi and Philips surrogate) is really carrying Shawn and Belle's baby. I also think while Shawn is having his fun with the hooker, Belle is going to get friendly with Benji, I know he is not on the show yet, but it always seems to be the new ones who are new in town (look at Willow) This will make a Shelle reunion a long time coming.
I too believe Sami will get pregnant with EJ's baby. She has not been pregnant since Will,(real life, yes) who by the way desparately needs a haircut, anyway, this will make the DiMera/Brady feud even more interesting. Together Sami and EJ will make Salem rock. EJ is already manipulating Sami into thinking her actions are not that bad. She will start to care less what her family thinks, thanks to EJ's brainwashing.
Patch will no doubt remember Kayla and start fighting for her, she will of course be interested in someone else.
I think if Max and Abby hook up it would create some exciting drama, especially since Abby and Chelsea are best friends. The three girls will be at each others throats, as long as Chelsea's throat is slashed, I don't care if who wins.
These too are JMO, but it's fun guessing!
