I don't know why people keep pointing to #FE saying it's lack of success means they're won't be a new console entry when it's very clearly a spin off. That's like saying the last Mario Party bombed so they're won't be any more console Mario games. Radiant Dawn isn't a good excuse either because it was from a time when FE was still considered a hardcore only franchise and was released on Wii.
Pointing it out as the Wii U does/did not have an RPG audience the RPG audience is on Portable/PC and PS4 and Nintendo knows it. RD/POR have the poorest sales in the series, and it's not a quality issue, it was an audience mismatch issue.
