Actually. I take that back. This isn't Sakurai 4D chess theory. Those aren't purple and yellow chairs. They've been intentionally hinting and teasing the whole time. It's their M.O. Tony literally tweeted about "liking Hockey" as a Jason nod. So whether or not those hint at future characters, it's still a part of their marketing game.
Yeah PFG is totally into this stealth teaser shit. They shoved the PPG in the corner for the Joker trailer, Tony explicitly used "buttercup" during the Discord Q&A, and they did all those banana-related tweets before revealing Banana Guard including a "look at the first letter of each word" tease. They are, to put it kinda unkindly, this kind of obnoxious, and intentionally so...even if it's blown up in their faces more often than not.
What made the whole chair theory dumb is that it doesn't fit Sakurai's profile to do that kinda shit. For some reason we've given him this reputation of being this master troll when in truth Sakurai's pretty straight-laced - playful, self-aware, and to some degree self-deprecating, but he doesn't actually do all this guerilla marketing stuff people think he does. Tony Huynh, meanwhile, has shown that he's totally into that shit, and that's an attitude that funnels all the way down.
So yeah, I can see these being Matrix and Watchmen teases. IIRC the Matrix stuff we knew beforehand just came from datamining so if anything I'm taking that as further proof.
Rorschach seems like a no-brainer, or Dr. Manhattan if they can cover his blue dong.
It would be hilarious if they gave Dr Manhattan a fig leaf or just a mosaic blur.
Dr. Manhattan had a black speedo for when he was doing "official superhero" stuff that'd make sense as a default.
