Shooters aren't "hardcore" games. Actually they are more casual than any other considered "hardcore" genre. Why? They have easy gameplay, and nothing to difficult to grasp about it.
But Nintendo has never really gotten into too many shooters because they are from a different time than the rest. They are before the PC age, where shooters were pretty much not that great. Really wasn't til Doom and Goldeneye 007(published by Nintendo) that the shooter craze came about. I mean Sony wasn't part of that age and you've only seen them recently jump onboard as well.
I'm sure Nintendo will make a shooter of their own sooner or late, seeing that no one counts Metroid Prime. I just hope if they make a shooter it's original, like Metroid Prime was. None of the stereotypical crap we keep getting. Luckily Nintendo is good with setting standards so I wouldn't worry too much about it.
