I disagree, it's about time that the DS expand it's horrizan. But there will be alot of angry GTA fans of seeing other games being made outside of Playstation, for them get a grip, there will be plenty more to come I'm pretty sure.
This is why I own more then 1 system brand. I use to be a Nintendo loyalist, still am in some ways. But unfortunately I'm getting older & my taste in entertainment matures. So when I wanna play something more grown up, I plug up my playstation & play some Grand Theft Auto. The thing is Nintendo is really meant for the kids & family. Sure they have some T & M rated games, but they can still stand to expand a little more (without of course going overboard or something). So until they come out with something more in your favor, it might be a sign that it's time to move on.
The series is fine the way that it is. But if they want a new twist, have Zelda playable under certain moments & conditions, or use some of the characters from Twilight Princess & make a game that has a Dragon Quest or Final Fantasy feel to it.
