The new package requires plus $50 for Live and plus ~$60(or more) for a decent HDD.
So totals based on their logic should be:
360 = $410
PS3 = $510 (however still has bigger HDD, bluray, no batteries, etc
Wii = $310 (About 5x the number of games included for this price, arguably better too)
Sorry, Wii is still by far the better valued product for games of this type.
Also, all those that whine about not needing subcontroller are silly. For the game listed, probably not, for games you want to play (FPS, etc) you're not going to want to hold an uncomfortable DS3 for long.
Realistically, Wii's should not even contain Wii Fit and should have Wii Play vs stand alone controller. PS3 should not have any subcontrollers for the game listed. 360 should have what I already added.
This would make the prices:
360 = $410
PS3 = $450 (Still has bigger HDD, bluray, no batteries, etc)
Wii = $270 (Still about 5x the number of games included for this price, arguably better too)
**********************
As for existing owners. I can understand existing PS3 owners needing PS3 Eye as it is very low on the sell through rate per PS3 owner, but seriously, does any Wii owner need another Wiimote/nunchuk to make 2players? Also, Wii Fit has a large sell through rate and its arguable wether the group that will potentially want Kinect wouldn't already have Wii Fit. So, Wii's price should $0 or at best $90.
