I really doubt Sony or MS will be able to produce a "true" Wii killer (whatever it is packaged with the console or not)
I mean the PS3 is too expensive for the family market (even 300$ will remain a bit too high) and even if the Xbox360 si cheap (arcade) it just doesn't have the appeal that Wii has ...
But if they succeed, yes, it will be a lot of cash for MS
Just look how they killed the ipod with their zune !!!!!!!!
... oh, wait, they did not ;)))
LESSON : It is very very very very hard to disturb a market after a recent disturbtion !
Time to Work !
