I think he's defensive because fighting games are more of a 90's thing. The only way this turns out to be a good seller is if they have found a way to make it an all new experience, not just fancy new graphics and kill animations. Just like Project Gotham Racing, fighting games always seem to make it back for a console launch...
Tell that to the EVO crowd and people who make a living off of fighting games like Daigo and Infilitration.
There have been quite a few fighting games the last few years and they seem to be doing well. Even the PC has been getting some fighters lately to, they just got MK and are getting Skullgirls as well.
It's just that simple.
