This is the 8 contenders & their first matches from what I have heard:
Orton vs Angle
Hardy vs Booker
Benoit vs Finlay
Henry vs Lashley
I think we know that Orton is out of the picture, and its highly doubtful that Finlay, Booker or Hardy will win.
This leaves Angle, Lashley, Henry & Benoit as the most likely winners!
Thankfully with Henry vs Lashley being a first round match, that means at least one of them is gonna be gone early on (and we are gonna be treated to what is probably gonna be the worst match of the year).
I will predict that first round winners are:
Angle
Hardy
Benoit
Lashley
Hopefully it will mean a Benoit vs Angle match in the second or final round!
Overall winner is gonna be Angle!
