Lol, at the people stating what will and won't be a success to Sony. All Sony wants to do is win by at least 300K, though, I see them winning by 400K+. Why? So they can shove it in MS's face by stating that the PS4 was the #1 console for the months of July-Nov in the US, basically stating they wiped away any gain MS made with firesales and exclusives.
And I can't believe people actually think its going to be close, as in less than 100K. We have great pre-order results for the Pro, confirmed by insiders on Gaf and Amazon results. For Sept, the Pro was the only console in the Top 20, and it actually finished in the Top 5. In Oct, it slipped out of the Top 20, but it still was the number one console on the monthly Bestsellers at #26. In Nov, it is currently back in the Top 20, at #17, only being surpassed by the PS4 Slim. Now, let's look at the current Top 20 rankings at Amazon, and other retailers.
Amazon - #1-PS4 UC4, #16-XBO Minecraft, #17-XBO BF1
Gamestop - #1-PS4 UC4+TLOU, #2-PS4 UC4+R&C, #16-XBO GeOW4
Target - #6-PS4 Pro, #8-XBO BF1, #20-PS4 UC4
Best Buy - #9-XBO BF1
Walmart - #2-XBO Minecraft, #3-PS4 UC4, #4-XBO The Division, #5-XBO BF1, #6-XBO BF1, #7-XBO BF1 (1TB), #20-PS4 Pro
You know what any sane person would take from those? That BF may be close, with maybe a slight PS4 lead (considering Amazon and Gamestop are a large chunk of the gaming market), but you include Pro pre-orders and it's an easy win for the PS4.
