I wouldn't have AA in a Championship match at BFG, personally. He's been good and all, but I don't think he's done much to deserve it. For a year he went over a pretty much non-existent X-Division, then started going over other people.
Roode/Storm is the TNA WHC match at BFG, that's the best way to go based off stories and whatnot- but I guess they ain't gonna let that happen.
I agree that Magnus and Joe should have a match there, I guess Joey and Snow too - though, I don't care for this storyline anymore, and I'm still baffled as to why he goes after the only person who told him /yes/, simply for kicking him out.
Tag team match - yes.
Kenny King vs Ion vs Sonjay for the X-Division title.
Bully Ray and Aries should have a number one contender's match, imo, for the TNA title.
And it should be Tara vs Tess, at BFG for the KO title.
