Will Nintendo have new IPs for 2008?

Wii Fit and Wii Music are old IP. Namely, uh, the Wii brand. It's been around for about a year, maybe you've heard of it. Just because they have different gameplay doesn't necesarily make them new IP, unless Mario Party is a seperate IP.

Hopefully Nintendo will still have some new IP next year, though.

If I get what you're saying, Wii Fit and Wii Music are not new IPs because the name of Wii is in their titles.  But if they had just named them Fit, Music, Draw, Sports and Play that would be 5 IPs since there isn't a common name to link them together.  And if it is not the name that links them together as an IP, what is it then?
