my best guess is that firstly, Bryan won't be added to the main event. i know many don't want it, but for me, i wouldn't hate it just because it would be great to see Bryan at least in the match, BUT i don't see it happening because i don't think WWE thinks Bryan's money and i see him NEVER winning the WWE title ever again. if he ever wins the title, i will be the most shocked person alive because i don't see WWE EVER giving him a title run again.....i want him to win the WWE title and have a REAL run with it, but it won't happen.
Secondly, my guess is that the announcement will likely be some type of either handicap match, tag match or one-on-one match vs. either Kane and Big Show or just the Big Show. i hope that's not the announcement, but i doubt Triple H will please the crowd by having Bryan vs. Reigns or Bryan vs. Lesnar....ANOTHER guess is Rollins could be put into a match against Reigns at Fast Lane....if that's the announcement, i won't hate it. Reigns vs. Rollins at Fast Lane for the WWE title match would be great to see.
