I'm just hoping this isnt another super let down like E3 direct was, that was painful. Since they say they're gonna be talking about upcoming games + three houses, Why do I feel were going to get like 30min of three houses and 5 min of everything else, just like E3 and Smash

Last year when announcing the March 8th Direct, they used the exact same wording about Mario Tennis:

Mario Tennis Aces was only shown for about six minutes.
