I read NeoGAF every day, own every Nintendo console, and can't think of anything else since Pikmin (excluding stuff like Wii Sports and Nintendogs). If there are some awesome new IPs that I don't know about, that's such bad marketing it's almost like they're doing anti-marketing.
If you're going back as far as Pikmin, you'd have to exclude:
- All non-EAD studios (Wonderful 101, Xenoblade, The Last Story, Pandora's Tower)
- Portable titles (Steel Diver, Codename STEAM)
- Download titles (Pushmo/Crashmo, Sakura Samurai, Harmoknight, Dillon's Rolling Western)
- Non-character based IPs (Wii Sports, Wii Music, Nintendogs, etc)
Not saying those are all
major IPs, or even internally developed in some cases, but they are properties produced and owned by Nintendo that have been developed since Wii. I'm probably missing some.
Yeah, marketing is a problem. Nintendo very often doesn't seem to know who is actually buying and playing their games. A good example of that is failing almost completely to show off the multiplayer in Devil's Third.
