The WWE 2K14 "30 years of Wrestlemania mode" roster was scheduled to be released today at WWE Axxess but IGN.com posted the roster this morning. Realizing a mistake was made, IGN quickly pulled the article but a fan was able to copy and paste the names which are as follows: 

Alberto Del Rio 
Andre the Giant 
Batista 
Big Show 
Big Show (Retro) 
Bret Hart 
Brock Lesnar 
Brock Lesnar (Retro) 
Chris Jericho

My guess is we will get

Shawn Michaels vs Ric Flair(24)

Triple H vs Brock Lesner(29)
Triple H vs Batista(21)

Goldberg vs. Lesnar?

Considering that's Goldberg's only Wrestlemania match, and he's in the game.
