After games like KH3 and FF15, I've learned a year really isn't a long time to be waiting for a game. Even if FE16 gets pushed back, that's usually a positive. Most of the time they get pushed back for the better. There's so many worries about it being lazy or having rushed writing, but at the same time you want the game asap. I'm just glad a console fire emblem is happening in the first place..
I'm not too worried about smash being announced first, it will sell more switches, in which will make said people who bought it for smash, will end up hopefully wanting other games for the console they just bought. I already expected to most likely hear about this fire emblem at e3.
If we are lucky, let's hope for an FE Direct. But, honestly things could be a lot worse than having to wait until June.
