It was reported that according to Andy Payne, the Leeds studio was created to take over development of all mobile versions of the COD franchise but not for the PS Vita, more details inside............
Andy said in an interview
“Activision are like a machine. I have to be careful what I say about these guys because I know them so well and they’ll cane me”
“They’re very good, and you know what, what people don’t realize with Activision is, the two studios working on the Call of Dutyfranchise are collaborative studios. That’s unheard of. All of the assets are reusable, so they’re not wasting time.”HOWEVER they recently confirmed that they will be working on the "mobile versions", they could be referring to the smartphone version and could exclude the PS Vita version which is a potential disappointment to Call Of Duty fans.
