Considering that World was more casual than hardcore fans would have liked, Rise has a lot of their established fanbase thirsty for another traditional entry. On the other side of that coin, World also got a lot of new people into the franchise in general. With both of those being a factor, and Rise being a MAJOR, console exclusive...I would say it is likely to beat AC in the short term. Those long term legs however is another discussion entirely.
I do think that lifetime, Rise will sell more than World on all platforms combined...or at the very least come very close to it.
