Big night tonight. Only 10 American Idol hopefuls are remaining, and after last night's performance by rocker David Cook, we imagine he (along with David Archuleta and Michael Johns) will last at least another week.

The rest of the gang, though? That we're not sure about!

Somebody's gotta get the boot tonight, and in our minds it will boil down to one of four - Jason Castro, Chikezie, Syesha Mercado and Ramiele Malubay.

Something tells us these four singers are more vulnerable then the other six, although Americans make that call, and they've shocked us many times before.

Who do you think will be the top and bottom vote-getters when American Idol announces its results tonight - and who will be heading for home?
