My Birthday Present

So, my birthday is comin' up. And what we do on my birthday is my parents let me go pick a gift and then they purchase said gift. Well, this year, I can't decide on a gift. There's so many good games out right now. The one's that I have my eye on right now are: Homefront: Fight for Freedom, Splinter Cell Conviction, Left 4 Dead 2, Assassin's Creed Brotherhood, or I could wait a bit till Gears of War 3 comes out. Feel free to tell me what you think I should get.
