Shulk was revealed in a Japanese only 3DS Nintendo Direct, so there's a precedent for a Japanese only reveal. The Game Awards also bodes well for region-focused reveals as it's primarily an American event.
So then what's the point of your argument?
Are you arguing for hope? If so, the pessimistic and cynical tone of your argument doesn't convey that at all, and it seems like you're bashing on Dragon Quest and Square Enix moreso than arguing for any sort of hope.
Are you arguing against hope? If so, why? You said it yourself that expectations are at an all time low, so why beat a dead horse? Regardless, the tone of your argument and use of exaggeration advocates more for despair than against hope. There's a clear difference between the two as one leads to bitter resentment whereas the other leads to realistic expectations, with the latter being preferred.
Low expectations aren't a bad thing; having low expectations leads to low disappointment. The fanbase was on track for that until the Grinch hoax skyrocketed hopes, and fans have similarly looked into Joker's reveal as a scapegoat for their wildest dreams when in reality that's simply not the case.
Surely your argument has to be doing something else because it's not about hope.
I think it would make sense to reveal a character now but not show gameplay like Joker. Having two characters revealed but without gameplay and a release date gives Nintendo the Q1 and Q2 directs to expand on the characters. It'd probably go something like this:
- November 2018: The Plant reveal, gameplay, release date
- December 2018, Joker reveal at TGAs, Erdrick reveal at Jump Festa 2019
- Q1 & Q2 2019: Joker and Erdrick gameplay, release dates
- E3 2019: Fighter 3 and Fighter 4 reveals, Fighter 3 gameplay and release date
- Q3 & Q4 2019: Fighter 4 gameplay and release date, Fighter 5 reveal
- Q1 2020: Fighter 5 gameplay and release date
I wouldn't be surprised if Erdrick comes with gameplay unlike Joker though. There's room for variability in Q1 & Q2 2019 for Erdrick's reveal, gameplay, and release date.
What do you mean "general players?" GameFAQs and 4chan? Those places are salt mines and will never be happy. A couple of trolls and frat boys will be mad about no Goku, but again, that's a minority.
I understand that the Smash Bros. fanbase is one of the most immature of them all, and people would certainly be mad and disappointed, but not for those reasons.
