DLC: personally not interested at all (and I doubt Nintendo will release DLC for their own retail games).
Episodic games: interested, already bought Tales of Monkey Island, Sam & Max Season 2 (both on PC).
I wouldn't mind buying episodic Wii games, but only if they either are exclusive on the system or have the same prize as the versions on other systems (negative example: Tales of Monkey Island, which is $/€ 50 on Wii for the complete game and $ 35 on PC).
