#5 The Bar (c) vs. The Miz and Shane McMahon - WWE SmackDown Tag Team Championship
This one is tough to predict as the Bar has been booked pretty strongly by WWE. Then again, the newly formed team of Shane McMahon and The Miz which claims to be 'The Best Tag Team in The World' is extremely engaging and the WWE Universe loves them. Also, they will most likely not be defeated in their first match.
The team of The Miz and Shane McMahon has a better chance of winning as they have entertained the audience with their new and refreshing gimmicks and the Smackdown tag team division needs some significant changes to make it enjoyable once again.
They will most likely win the titles and lose them at a future PPV due to some misunderstanding which will ignite a feud between them and that feud can reach its conclusion at 'The Grandest Stage Of Them All'.
Prediction - The Miz and Shane Mcmahon defeat The Bar and become the new SmackDown Tag Team Champions
