People shouldn't forget that we're talking about the 2018-2019 fiscal that ends at the end of March for Nintendo.
So it got plenty of times to do that :P Also, they're probably gonna push out FE Three Houses for the beginning of 2019 (Feb/Mar). That's 2 other decent games to look foward that can push sales.
No because their FE trailer said "Spring 2019". Spring begins March 21 so at the very earliest you'd only get 1-2 weeks of sales.
We got an interview where they confirmed the titles they showed during E3 where all coming in the next 6-9 months, which means late March at worst.
Anywoo, we also have other Directs to look at before even looking at this vague briefing we got there. Pretty sure we'll get at least 1 port and 1 new game in between too.
