On average, Canadians so far have purchased approximately three games for every PS4 or Xbox One sold; that number is 11 percent less than when the PS3 and Xbox 360 launched.
Despite this drop in average number of games being sold for each system, the sales results for the latest consoles remain very strong eight months after launch. Comparing the launch this past year with the previous launch of the Xbox 360 and PS3, console sales in Canada have never been stronger. Combined these two systems have outsold their predecessors during launch by 127 percent. Along with strong console sales, software sales have doubled versus previous launches, with sales up 102 percent. Accessory sales, although up 29 percent, remain the softest area of growth for these new systems.
I'm new so I am not sure if I can post a link, but over on DailyTech the author states the PS4 is 2:1 in hardware and 3:1 in software sales compared to the Xbox One. Gives several reasons as to why as well.
It looks like he is pulling numbers out of no where in some paragraphs though. Last I knew from this thread and the GAF in general was it was around 9 million to Ones 5 +/- million.
I wouldn't be surprised if the USA numbers are close for Destiny between PS4 and XB1. Xbox platform has a lot of Bungie fans. Worldwide is a different story. The Destiny deal is beneficial for all involved.
1) To help Sony secure a bigger shooter foot hold in the USA
2) For Activision/Bungie to access consumers outside of the USA and UK.
