Aight, predictions for the next three months, and be sure to specify if it’s a regular direct, surprise stream, or dedicated Smash Direct for each month. Go!
As for mine:
September: General Nintendo Direct. Smash reveals: Elma (immediately after Torna release trailer and/or X Switch Port announcement), quick Isabelle Echo announcement following the Animal Crossing Switch title announcement (title card only, no trailer), Bandana Waddle Dee (named Waddle Dee, shown off at the end). They’ll also in general discuss online.
October: Surprise stream - Neku reveal to tie in to TWEWY Final Remix release
November: 50 facts Smash dedicated Direct, GIANT blowout. Isaac, RH Rep, Ken, Shadow, Zack, Incineroar, second Bandai Namco rep (probably Lloyd Irving). Spirits mode discussed. All Star mode, remaining ATs revealed (including a Fatal Frame AT) and maybe some more bosses. Ends with WIP 3D models of Rex and Pyra and a title card saying “Rex & Pyra are on the way!!” revealing the start of the DLC Period. Rex & Pyra will be available from the eShop in February 2019.
