"Here is the North American sales data for the top 10 professional wrestling DVDs. Despite the absolute and total lack of promotion by WWE management, the ECW DVD is within 4,000 DVDs sold of being WWE's largest selling DVD of all time, trailing only the Wrestlemania XX DVD.

WRESTLEMANIA XX --- 113,548
RISE AND FALL OF ECW --- 109,444
ULTIMATE RIC FLAIR COLLECTION --- 94,952
MONDAY NIGHT WAR--- 87,228
WRESTLEMANIA 19 --- 58,642
FROM THE VAULT-SHAWN MICHAELS --- 54,999
MICK FOLEYS GREATEST HITS AND MISSES --- 53,661
BLOODBATH-WRESTLINGS MOST INCREDIBLE --- 49,333
DIVAS UNDRESSED --- 42,481
WWE-HULK STILL RULES --- 40,878"

Take that WWE.

Now on to my ROH DVD question, realistically, about how many units do you think that ROH moves for most of their DVD's?? I can't seem to place a finger on a realistic number, even as a guess. What do you guys think?
