The terms hardcore/casual are always hard to define and vastly overused. For some people is it genre of game played, for others it is total amount of time, or total number of titles purchased.
For most people, a person who plays CoD4 for 3 hours a day is hardcore. Another person who plays Nintendogs/Brain Training for 3 hours a day is casual. Why the difference? That is what they are pointing out.
