From a UK perspective, the problem is that "pants" can be used to say something is rubbish, or similar. We might say "that new Yahoo Mail design is a load of pants". With the Wii example, there is not the same sort of common use in any country I know of. (Maybe there is, but I don't know) So, OK, it is amusing and probably memorable, but as I Brit I would have tell them that they don't want a bunch of Brits saying their product is a load of pants. So, anything else, and it might be slightly clever marketing, but in this specific, I'd put my sensible head on and say they should avoid it.
