Looking at how things are at the moment I remember Nintendo's 3 pillar strategy. With the advent of the Wii U the 3 pillar concept is alive once again. However, it isn't limited to just Nintendo; nope the other big guys are currently having or gonna have their 3 pillar strategy quite soon. Lets start:
NINTENDO:
Wii(~95mil), 3DS(~22mil), and upcoming Wii U(5-8mil units sold by Christmas2012?)
vs
SONY:
PS2 (100+mil), PSV(3mil), and PS3 (67mil)
vs
MICROSOFT:
X360 (69mil), Surface/Windows8 (???), and Kinect(30mil) or X720 (???)
who has the best 3 pillar out of the big 3?
