is that true? I remmeber many Japanese localization confirmation via Directs for the 3DS and also SEGA games for Wii U.
In terms of "official" scope? Maybe but Summer is usually a dead period for new releases and Directs too. So it is pretty safe to assume that they will cover details, edition and dates for games such as Mario&Sonic 3DS/Wii U (one is march, the other June, so that's enough to cover up to summer), Zelda TPHD, Pokken, Star Fox, Minecraft Nintendo edition (pretty safe bet imho), Hyrule Warriors Legends and other 3DS games (Federation Force?)
I still don't know when #FE will be released: hopefully within summer and will be covered tomorrow.
But there will be no Pokemon Sun/Moon, no Zelda U (unless they would like to anticipate a small tidbit during the Zelda TP HD wolf link amiibo footage), no Paper Mario U and obviously no NX.
Let's take a look at Trev lineup to better understadn what could be covered during the "Spring/summer Direct" of tomorrow:
