I'd say no their not spoiled, in fact there starved.
I base this on my sister who is your typical core Nintendo owner, not casual by any sense of the word, but also not one that even visits sites like VG. She only owned the Gamecube and was very happy with the games on it, she didn't bother getting a PS2.
She recently got a PS3 slim...I asked her why and she simply said that the wii wasn't satisfying her gaming needs...that it was going to casual, and that surprising the PS3 happened to have games she liked. She still owns more wii games, but her PS3 collection is growing exponential.
Now I'm not saying that she represents all wii core owners, but more like there are many nintendo supporters like her going the multi-console route to get their gaming hit.
