Which RPG will do better Fire Emblem x Shin Megami Tensei or Xenoblade Chronicles X in sales?

[Shortiloe]

First of all: It is called Shin Megami Tensei X Fire Emblem and NOT(!!!) Fire Emblem X Shin Megami Tensei.

Second: we haven't seen ANYTHING from SMT X FE, so no comparison/prediction possible. /Thread.
