I could see maybe something like
$199.99 w/Wii Sports
$279.99 w/Wii Sports + New Super Mario Bros. Wii + extra controller (available in white or black)
But the $199.99 base pack w/Wii Sports is going to stay. No way Nintendo takes that out of the box, because too many people associate that with the Wii and would probably freak out if they bought the system, got it home, and found out that Wii Sports wasn't in there (and yes, people are that stupid).
The thing is though I don't think Nintendo likes to bundle too many games at once because it may discourage people from buying other software.
Where Nintendo is probably making a killing right now is accessorie sales ... every Wii purchase right now means a Wiimote or Wii Play purchase + a nunchaku purchase .... which is likely a huge profit margin at $60 between those two. So they may not want to bundle controllers either.
Consumers are impulsive creatures ... they go into a Best Buy not wanting to spend too much, but see the Wii at a new low price of $199.99 ... so they grab that ... but now you need that extra controller ... grab that .... oh NEW SUPER MARIO BROS. WII .... gotta have that .... by the end of the hour they're putting down $500 on their credit card.
That's what Nintendo wants ... very rarely do people just buy the system alone, and Nintendo is probably leaning more on fat profits from things like the $20 nunchaku (probably costs them like $2 to make) and $10 more for Wii Fit Plus to offset the $50 price cut.
