Seriously, off the top of my head, these people are bigger "stars" than Cody:

John Cena
CM Punk
Ryback
Chris Jericho
Sheamus
Dolph Ziggler
Randy Orton
Daniel Bryan
Kane
Rey Mysterio
Big Show
The Miz
Damien Sandow (more heat and is a better wrestler)

Not to mention the part timers: The Rock, Brock Lesnar, Triple H, The Undertaker...

A lot of the people on the above list aren't even stars, so not sure how Cody falls into that category. Not saying he can't or isn't going to get there, but he's not there now and it's a while away (no sooner than a year) if it happens.
