I think we had another thread for this before...but I'll answer again anyway.
Right now, it seems to me that Xenoblade Chronicles X will sell more. Fire Emblem and SMT both have loyal fanbases, but the games themselves are very different, both in setting and gameplay. Unless they find a way to fuse the gameplay styles, it seems to me like one fanbase will be expected to cave to another style or setting. I just can't see fans of both franchises rushing to play something drastically different than what they're used to.
X on the other hand, seems to be following the same vein as its predecessor, a game that was received extremely well both among critics and fans, and is receiving a lot more hype at the moment.
This could change...obviously, but this is just how I see things right now.
