A couple possible trades that I am kind of hoping for and could possibly see happening are:

Artest for Peja (and fillers whatever): This has been thrown around for a while now.

Artest for Bosh (and fillers): Bosh just said how he's not sure he wants to stay in Toronto, who would. This might also help Toronto by actually getting some publicity and something in return for Bosh before he heads out. God i really hope we get Bosh.
