My household is a multiconsole owning one. Both of them actually 
Both my dad and stepmom, and my real mom own a Wii each, but they are rarely used. Right now, I'm a PS3 only owner, but I plan on expanding to the other consoles once I have the cash.
Having said all that, I think maybe some 30% of current console owners will have more than one console from this generation.
