coming in late so I don't know if this has been pointed out already or not. But for the unfication match...the WWE title as we know it now is actually the wwe undisputed championship after the old wwe and wcw titles where unified the first time (I.E. they didn't want to keep carrying around both the wwe and heavyweight belts everywhere), the
pre-spinner belt supposed to represent both the wwe and the wcw world heavyweight tittles. I know this was sort negated when they brought back the World Heavyweight Title anyways, but technically the wwe title is still the undisputed championship since they never officially retconed that.
which means,(I.E. what I'm trying to get at) is if they have a match unifying the titles, it means the world heavy weight title will be combined with the title that is in itself a combination of the world heavy weight and wwe titles. I can only theorize that this will either create some sort of temporal loop, as the world heavyweight title will in a way be unified with itself creating a paradox, or the new edlrich abomination of a title will technically be the unified unified, undisputed undisputed championship.....undisputeception!
guys...we must go deeper.
