The Wii is a great console, but Nintendo needs to branch out to a more mature audience. I am sure with the next console they make, hopefully it will be a more mature nintendo. I am not saying that the gameplay is bad, its just different. And honestly, I love my Wii, Super Smash Bros FTW.
I don't think they need to. This has been Nintendo's market for over 20 years and its still making them oodles of cash. You cater to a specific market. Nickelodeon doesn't air CSI. Just...different markets.
The third parties have always been responsible for bringing that content to Nintendo consoles, they're....just....not doing that now. Which makes no sense. Because you'd want your games on the console with the most marketshare. You'd sell more.
I love my Wii. Only game I have that I truly regret is Sonic and the Secret Rings. Unplayable pile of garbage. (Also Sin & Punishment, but that's on the virtual console).

All games I have/beaten/played and enjoyed. I still have to play Tales of Symphonia: Dawn of the New World. Haven't started it yet.
Games I'm interested in picking up? A Boy and His Blob, Boom Blox: Bash Party, Cave Story, Chibi-Robo! - New Play Control!, The Conduit, Donkey Kong: Jungle Beat - New Play Control!, Klonoa: Door to Phantomile, "The Legend of Zelda", Melee! Pokémon Scramble, Metroid: Other M, New Super Mario Bros. Wii, Pikmin 3, Punch-Out!!, Resident Evil Zero: Wii Edition, Super Mario Galaxy 2, Tales of Monkey Island.
That's not a poor library.
The DS however is a mess. I look forward to like...one game a year on that platform. It's sad.
