That darn little white box is so cheap, that it makes us PS3/360 owners look bad. . .
Seriously though, I would probably guess that it could be sold even cheaper given that the main technology (not Wii-mote) isn't as new and advanced as the PS3 or 360.
*edit* - Well, I had tried to answer just the question of the thread itself without really reading it... Now that I have read the post, I'm pretty confused as to the direction the poster is going. Is it bait or something?
