If someone posts a list of ALL Titles releasing in the digital space as well (including console debuts), on both consoles, that list for Xbox One is going to only look more sparse. Or at least the difference in games released on both platforms is simply going to grow larger in that list.
Here is a link to the list you wanted. When I look at
this site for the number of
upcoming exclusive games for both consoles, Retail and Digital Exclusives including releases on PC, the numbers are:
PS4 with 23 upcoming exclusives
Xbox one with 7 upcoming exclusives
