Michael Buble
Albums: Next studio album, I expect him to go #1 in at least 10 countries, and sell 3-4M copies in one year.
Singles: Well, his singles always fail, but his videos are iconic though
Tour: NOW this is where games are serious. He sold out 140,000 tickets in O2 arena alone: his tour already made $7-10 million from those dates alone. He's definitely extend dates throughout the world.
Christmas album: Of course, Christmas will finally cross the 10M mark this year - it's amazing how this album became such a timeless classic in 17 weeks; I mean 9 million copies sold? That's unbelievable.
Mariah
Music: Finally get her 19th number 1 in the US. Release the biggest hit of her career worldwide and slay like On The Floor.
And umm.. keep up the good witty fight between her and Nicki.
