Here's a gem from GameFAQs: http://www.gamefaqs.com/boards/936978-dead-or-alive-5/62007471/691392418
DOA4 came out in 2005 when the console was very expensive and there were only around 5 - 6 million users. This is the year 2012 with 30 MILLION xbox live users, millions of consoles sold. I bet you almost everyone is sick of street fighter, tekken, and soul calibur by now. The last DOA was 6 years ago, when this one launches everyone will be jumping on the DOA bandwagon in a second especially now that this ones multiplatform, new graphics, new level destruction.
too bad for anyone new to the series, the counter system takes at least a couple years to get down at a pro level, its not just blocking like in street fighter, theres tons and tons and tons of stuff to learn when it comes to defense in offense, and im going to all the tourneys with my doa4 years of training and getting that cash money
