Is this their next Pay per view? I'm pretty sure they have a Sept. one, yet their rarely ever updated website isn't listing one.
Regardless, if it seems to me Kurt Angle will defend his Championship against Bobby Lashley and for no other reason than because thats what everyone has been asking for, since back in the WWE. Will it be worth anything? I honestly doubt it. I mean, to me Lashley is already failing because he's wearing boxer shorts. I can't stand when Wrestlers go half assed and don't even wear actual "wrestling tights". He just looks stupid in boxer shorts.

While I'm not convinced the shorts alone will cause the match to be a massive failure, I am convinced that Lashley has no true desire to be in the sport of Pro Wrestling anymore and is purely doing this for a better connection in the world of MMA, and the connection it seems TNA has with them. That and money.
Someone mentioned a possible "Retirement match" up above. While I think Sting could very well be involved in a match-up like that, I don't believe it'd be against a lack luster shit fest like Matt Morgan - but instead, against a newly turned dastardly heel; A.J. Styles.
As for the Tag team Championships, I'm assuming a Fatal Four Way. Scott Steiner/Booker T, Beer Money, British Invasion & Team 3D. I'm running out of reasons as to why this should/would be what it seems, other than to say these are the top four teams they've been pushing for the previous year and it only makes sense to have them meet in one big match. Be it elimination, or otherwise.
Samoa Joe could defend the X-Division title against Christopher Daniels & A.J. Styles, but only if Styles hasn't turned heel on Sting yet - which I still believe is coming more than Styles falling back into the X-Division. I think instead it could be Joe, Daniels, Suicide & The Pope in another Four Way - Ultimate X match. Once again for no other reason than it makes sense due to the fact that these four individuals are separately feuding with one another right now, and TNA has a major lack of moving on to new things, so much as just "connection" feuds.
