With Shulk and other Xenoblade stuff in Smash, I think it will have an "Fire Emblem Affect" where more people are interested and buy the games.
I'm hoping it goes like this: XCX > XC 3D > XC because XC was spread mostly by word of mouth/internet and was limited and the sales aren't good. XC 3D is exclusive to NN 3DS so that may affect it slightly, but I think with Smash and a decent install base it should do just fine.
Lastly, XCX has hype and is the newest and biggest game on Wii U and deserves to win.
