He's slightly right. The Wii was established in the market without many of these types of games and that has had many effects, but the two interesting ones are:Sadist said:
1) People who are specifically seeking out those types of games have likely purchased a PS3 or 360 for that purpose.
2) People who might be interested, own a Wii, and haven't picked up a PS3 or 360 for those types of experiences don't have their eyes open for them since they're not terribly expected.... GAF members excepted.
Hopefully third parties are so stupid as to write Nintendo off completely, and will focus a lot of that type of support to their next system in it's first year. Self fulfilling prophecies I tell ya.
EDIT: These types of games being bloody, violent, and full of dick and fart jokes.
