Originally WWE had December 21^st listed for WWE Armageddon PPV, recently it was changed to December 14^th.

TNA's Turning Point PPV was originally slated for December 14^th, but they have changed theirs to December 21^st.

From what I understand the Cable companies will not allow two wrestling PPV's to run on the same day.

So I have been told the two companies decided to exchange the dates.

This is a listing from WWE.com site:
