Having too many exclusives to publish may not necessarily be a problem, but when you neglect to give them proper marketing, it's time to stop and think.
After a number of the major third party PS2 supporters have headed toward multiplatform development, Sony is left to deliver the bulk of the PS3's console-selling titles. In the previous generation, the Jak & Daxter games were solid offerings that helped PS2 cover its bases, but now developers like Naughty Dog are in a position where PS3 owners are looking to them for must-have exclusives.
LittleBigPlanet 2 launches in 4 days. The Kevin Butler ad just started airing and there's nothing else in the way of advertising that Sony has, aside from a few redecorated websites.
Killzone 3 launches in just over a month. Yet only the biggest PS3 fans know much about it. A month before Halo Reach launched, Microsoft was already in viral mode.
And what about Ico + SotC, Motorstorm Apocalypse, and now Socom 4? All of them are due in the next 3 months.
When NPD numbers are posted and they indicate Xbox 360 outsold PS3 by 88% in December, and Kinect software outsold Move software 13 to 1, it's not as if I can't figure out why.
Apparently, Sony just doesn't give a fuck.
