Not really, the new options are nice but are pretty minor in the grand scheme of things and aren't quite the kind of stuff you would really want. It's kind of baffling to me that they didn't incorporate the new invite friend feature the Switch has, though maybe it wasn't available in time
Of course. Nothing can stop the Slayer. Not the hordes of hell, or the armies of heaven, nor a measly Smash hoax. He'll rip and tear his way into Smash Ultimate one day.
Hard to say. I'd guess 4-5. They wouldn't announce it as early as September if it was only 2, I don't think.
3. At launch the game was data-mined to show WOL had space for up to 16 new characters. This would fit in 3 Fighter Passes plus Piranha Plant.
Honestly, I see no reason why Travis couldn't be the fifth fighter. This idea, that I've commonly seen in this thread, that the audience of TGA (if we're assuming that's when fighter 5 is revealed) have about as much VG knowledge as my mother, that they'd barely recognise any character not called Super Mario, is rather daft. It's a gaming show, one would expect the audience to have some VG knowledge that they can broadly recognise most main characters.
I really hope that we would get 5 characters in Wave 2; regardless of Fighter Pass #2 or not. Also I hope that Sakurai would able to fill out all slots in WoL and Attack Param (which had 16 slots) so that meant 10 more characters after 5th Fighter Pass 1 character and it's enough to split into Fighter Pass 2 and Fighter Pass 3.
A number of people seem to act like we're going to get another fighters pass (or at least the same number of characters as the fighters pass). But we'll definitely need confirmation first. (A shame Nintendo seems to be waiting to give us these details.)
As a general note, most of the videos posted by this account use the Turbo Mod (allowing you to cancel any attacks with another attack) and isn't an accurate representative of actual Ultimate play.
