TNA has already put up thier PPV subsite for next month's Lockdown PPV which takes place in the St. Louis area at the Family Arena. The site features Angle and Joe back to back with a preview video in the middle. The top right of the page reads "Every War Ends in the Cage". This leads me to believe that we might see Joe/Angle again and for the 4th time at this PPV but we shall see.
