Benji seemed less certain of this, but he brought up the PC sales. The original guy, who claims to have insider info for Gamestop nationwide, agreed that he can’t speak to the PC sales with his original quote (tho he did say ps4 + XBO to begin with).
Later in the thread, Benji said: “So, it's possible GoW may face some wide spread shortages at launch. Depends what sell through is like but shipments don't look like they are equaling what demand will be imo
Also the GoW Pro is pretry limited all things considered. Wide spread sell outs likely within 48 hours”
In response, Mat Piscatella (NPD Insider) said: “So, I think we can go to high confidence that GoW will be the biggest exclusive launch on PS4 so far. Only question is how high is the sky.”
That means >2.7 mill first week to surpass Uncharted 4.
