If we look at it and say ps4 is selling on average 140k every week right now. A 100% increase is 280k. No way is it going over a 150% increase. Just seems really crazy to assume that. And what a 200% increase would be 420k? Seems too crazy to be true.
Would be amazing if it happened and I will gladly eat my helping of crow.
But 140k is more like its baseline, not average. I suspect the week before Destiny might be something like 170-180k. Also, you're forgetting about the white PS4. Game is going to sell at least 2m week one on PS4 alone, if that doesn't cause a 200% increase I don't know what will!!
