I read that in Wendy's voice.Nah, I don't think they'll spread out Smash Bros info across two directs.
If I had to predict, I expect all remaining Smash Bros info to be revealed this week, and it will be the final roster.
As far as I know, that 'Grinch' banner is missing multiple characters. At least two characters. Which is why I don't believe that banner at all.
