I enjoyed Awakening and thought Fates was alright, but if this game is its own thing, or more similar to the GBA era, it'll be a pleasant suprise. Unfortunately, since the series recieved a massive spike in popularity when Awakening came out I doubt this will happen.
Other than the level design I don't dislike anything about the modern Fire Emblem games' gameplay. If the characters and writing see an improvement and the game has less annoying fanservice, it could be one of the better Fire Emblem games. I think too much influence from fates could hurt the game a bit, but in my opinion as long as it doesn't take too much from the worsts parts of Fates (mostly writing), it'll probably be fine. I'll probably get some amount of enjoyment out of it no matter what happens.
