Sakurai promises to show 50 facts that we've never heard/seen before but this is hugely subjective. What if it means 50 facts he hasn't mentioned before in his Picture of the Day miiverse and Smashbros.com posts? If so, he can decide to talk about the secret newcomers and present each of those characters' moves as facts. Or maybe he won't do that because some people have already unlocked all the secret characters in the 3DS game?
What do you think Sakurai means when he says there will be 50 new facts?
edit: The inspiration of Sakurai presenting newcomers and their moves as facts came from this miiverse post for Wednesday:
Pic of day: Here's what's happening behind the scenes in one of the secret fighter's shooting moves. The object being held is called an NES Zapper. This is an accessory which was released for the NES outside of Japan. Now, this image is edited, but it's a scene from the secret fighter's reveal video.
As you can see, Sakurai has reveal trailers for the secret newcomers. He could be using these for the direct this Thursday as part of the 50 new facts.
Here's the pic of the day below:
edit 2: In today's pic of day (whch is cool) he calls the direct "50 Must-See Things" as well. Looks like I may have been to pessimistic? His definition of Must-see may be different to our opinion but its sounds better than presenting 50 new facts.
Here's Oct 23rd Pic of Day below:
Pic of day: The giant screen in the Boxing Ring stage for Wii U reenacts the multiscreen effect seen in the arcade version of Punch-Out!! Looks like their aliases are displayed on the screen too.
