I agree with this ^^ ^^. Also last year after my brother and I got pretty good at the game - 8 out of 10 fights (3 rounds) would go to the cards. We hardly ever had straight KOs, - the 20% or so of fights that were finished were mostly submissions or TKOs. Against the CPU that was a different story because the AI was not very good and were very easy to KO.
That was prob due to the fact that we were both good at the game and a a similar skill level. I guarantee if you go in to this years slugging out toe to toe- the same thing will happen that was in 2010- someone will get KO'd. It'll be as sim as you want it to be or not be.
It's nice they added in a few features to make it more sim . .. but my experience last year was fairly sim based on how we approached fights, could've used some tweaking but as our skill levels got higher . .. our KOs went down drastically , just sayin'
