Previously WWE.com's pay-per-view schedule section only had the current PPV (and last week was just listing SummerSlam), but when I checked it out today...I noticed a much more extensive listing:
-Unforgiven [RAW] September 18, 2005 from Ford Center in Oklahoma City, OK -No Mercy [Smackdown] October 9, 2005 from Toyota Center in Houston, TX -Taboo Tuesday [RAW] (Tuesday) November 1, 2005 from PayOne Center in San Diego, CA -Survivor Series [Dual] November 27, 2005 from Joe Louis Arena in Detroit, MI -Armageddon [Smackdown] December 18, 2005 from Dunkin Donuts Center in Providence, RI -New Year's Revolution [RAW] January 8, 2006 from Pepsi Arena in Albany, NY -Royal Rumble [Dual] January 29, 2006 from American Airlines Arena in Miami, FL -No Way Out [Smackdown] February 19, 2006 from 1st Mariner Arena in Baltimore, MD -WrestleMania 22 [Dual] April 2, 2006 from Allstate Arena in Chicago, IL -Backlash [RAW] April 30, 2006 from Rupp Arena in Lexington, KY
Also, WWE released their updated Key Business Drivers on their Investor Relations website today: The Great American Bash did slightly over 225,000 buys (almost exactly on-par with Smackdown's last offering, Judgment Day).
Likely biased because I saw it happen, but 1 Oct 05, Samoa Joe vs. Kenta Kobashi. In light of my falling out of love with wrestling over the past year or two, that's probably the best match I'll ever see up close.
