Just wait till E3, dont worry it'll happen. Even Ninty themselves says they have several games in stored for core gamers. I can sure about japanese 3rd parties but I doubt western 3rd parties, they'll be the one who first crushed though...
end of core gaming days prediction:
E3 2006-The beginning of the end. Wii introduced
E3 2008- Armageddon. Wii motion plus introduced. Wii Music. Reggie says Animal crossing was a core game. Massive disappointment. many Wii core gamers selling their Wii.
E3 2010- Tape runs out
