"Breaking down the company's revenues by platform, the PlayStation 4 accounted for 36 percent of all sales, more than twice that of any other system. The Xbox One and PlayStation 3 were next with 17 percent of sales each, while the PC and Xbox 360 trailed with 14 percent each. Ubisoft executives cautioned that this skewing toward the PS4 may not reflect the overall market due to a promotion that saw a handful of Watch Dogs missions available only to players on Sony platforms."
Thought this paragraph might interest, considering historically Ac is a massive seller on XB360 and PS3 a dedicated title for those platforms might do well.
