Yeah, I wouldn't worry about it.
First off, Nintendo makes pretty damn solid machines. I know many people with working NES and SNES machines. And many more with dead or dying PS2s.
Secondly, the only way you'd 'lose' a vc/wiiware game is if they had to replace your wii, and then as mentioned you let them know you have some vc/ww games and they'll make sure to transfer them to the new Wii for you. I can't see them ever charging for that.
