My 2016 predictions:
Stacey gets sectioned leaving Martin to care for Lily and Arthur. Lily becomes very difficult. Shabs breaks up with Kush. Shabs tells Martin Kush is the father. Kush goes for custody of Arthur. I can't decide if Kush will use Arthur / trying to get Arthur as a means of getting Shabs back or if he will end up with Stacey.
Either way, Martin is soooo boring, I wish he'd leave!!
Kat's son Luke will turn out to be the Luke that Stacey dated. Once Stacey is better, she will be attracted to him and they will start a relationship (like Sharon and dead hubby / brother Denny). Alfie will suddenly collapse and Kat will discover the truth about his illness. Alfie might be 2016 Xmas death, reminiscent of nana moon dying.
Claudette and Sharon's dad were gangsters together, or possibly, he was her pimp. Vincent will look for his father and find him alive. The father was also a grass (possibly grassing up Sharon's dad?) and had to leave to go into hiding, which is why Claudette hates grasses so much.
Sharon's father will return properly and will go after Vincent / Claudette and Phil for some reason. Mitchells and Hubbards will become allies with Sharon caught in the middle.
Mick and Witney will have an affair. Mick will become very self destructive when he is found out. He will be ostracised and possibly homeless.
Denise will find Jordan who is having problems and he will come to live with her. He will be a big trouble maker and v manipulative like Lucas. Lucas will get early release for good behaviour and will use Jordan to try to worm his way back in.
Ronnie and Jack will continue their relationship. It will emerge that Jack is working for the police and has come out of retirement to investigate her for the disappearance of Charlie & roxy's BF who she murdered. Ronnie finds out his plans and rekindles her affair with Vincent so he can help her out. Maybe she kills Jack? Probably tied in with Hubbards storyline.
Roxy's returns at some point, with a new BF.
Sonia & her gf get married and try to adopt.
Lauren & Peter return.
Can you tell I'm bored today 
Anyone else got any other predictions??
