To be honest DQ11 did underperform on 3DS.
You can say 3DS was on its "twilight years" already, but it didn't stop Pokemon USUM to sell well.
Oh it totally underperformed on 3DS. I said so a few posts up. I still pin this on SE for not launching earlier if the goal was to match old titles. Obviously DQ9 was out of the question but 7 and 8 is on them. Maybe the plan is to make it up in the west but I feel like its an ill advised plan.
