but wii 2 is going to gain sales. wil ps3 and 360 will just keep going down. and when ps4/720 do release they will be competing with a platform that has a huge base. 

if wii 2 didnt mean ps4/720 then nintendo woudnt release it so soon,

you could argue that Wii2 is competing with platforms with huge base too, it goes both ways....

Especially if it mainly gets port from PS3/360 games...
