Creating New IPs Dilutes Nintendo's Franchise Output

[Pavolink]

Nintendo has released a lot of new IP's in the last years.
But there are two problems:
1. Those new IP's are not as big as the old ones (logically, taking in count that some of those have even 25 years)
2. The big ones like Wii Sports and Wii Fit are just hated because aren't AAA/blockbuster/cinematic or whatever other reason.

Also, 3DS has to much Mario:
Super Mario 3D Land, Mario Kart 7, Mario Tennis, New Super Mario Bros 2, Paper Mario and next year Luigi Mansion.
