It depends on your definition of hardcore.
Core gamers last gen were the guys that played insane amounts of hours and bought lots of games.
Now with Nintendo's new push, the former casual players have become core players and the non gamers are becoming casual players (people who normally do not play games that are playing Wii) at least that's the plan.
So there really should be 3 categories of players, not 2.
Hardcore player- People who buy lots and lots of games and are mostly attracted to certain types of games (games that they play through and beat and not just play them as a passtime).
Core players- People who buy games but go by what's hyped, or what's big and they also have an interest in licenesed movie games or sports games and such to a greater extent than the last group.
Casual players- the new casual players are the ones that either did not play games at all before or very rarely did and now are into the Wii because of that type of game and the controls and such.
In this sense, both the 360 and PS3 mostly cater to the core and hardcore audience with a few exceptions (Scene it, maybe Viva Pinata if it's bought by a kid, Buzz or Singstar).
The Wii is the only one catering in a huge way to the new casuals with a lot more casual-centric games coming out.
Thanks to Blacksaber for the sig!
