I'm kinda thinking Nintendo will announce a Super Smash Bros. Direct for this week, but I get the feeling the announcement isn't going to be tomorrow just based on the chaos that would ensue for us Westerners. My guess is that it would be announced either Tuesday or Wednesday, with the Direct scheduled for Wednesday or Thursday respectively.
What I'm hoping, personally, is that the Direct covers Joker, the other content including in the 3.0 update (stage builder, Home Run contest, maybe even Target Smash) and then get Erdrick revealed at the end or even during it. Maybe some amiibo news as well.
Frankly, while I haven't been here as often, I'm over the talk of who Brave is. The fans already mostly know who it is. But I'd like E3 to be a complete blank slate. Any hinting of certain characters can be completely fresh and new to everybody. Although, I'm sure SOMETHING will be found in the next patch that will leave more codenames.
At least that will be the official start of the "post-Vergeben" era, and with that being the beginning of the end of Smash speculation for me personally, it'll at least be interesting to close out with.
