The numbers aren't that good to be honest neither version (XB1 or PS4) is in the top 15 but they are both in the top 20. Its kind of funny the XB1 version is 18th and the PS4 version is 19th with less than 2k preorders separating them.
The high being 46k the low being 44.6k Added together they barely beat Bloodbornes numbers and are completely stomped by Arkham Knight on just the PS4, not sure what happened or if I missed something about AK but its numbers jumped significantly last week.
Evolve is very fun and if they can add more monsters, maps and hunters over time I can see it having a strong cult following and doing very well for the studio. Not so sure about how its initial sales will look though.
Edited to add:
Pre Order numbers are pretty deceptive, as a general rule if we got 46k pre orders we will generally sell 3/4ths or less of that actual number unless its a very established franchise.
