Pokemon tends to do its own thing and run on its own time, so I imagine maybe something will come if they do an individual Pokemon news reveal at some point. It's not often they do big info reveals at E3 usually.
I am surprised nothing about even Legends: Arceus has been revealed yet though. You'd think given how much of a big deal it is being such a unique and ambitious mainline entry in the franchise, and how much anticipation and questions there are for such a unique title that we have no idea what to expect from, there's gotta be stuff to reveal about that at least. Legends is such a game shrouded in mystery right now, that you'd think they'd say something about it or reveal some info about it at this point.
Or maybe, they really do want to surprise us with the game when we actually get to experience it and they don't want to spoil the experience too much. Who knows?
Either way, they ought to be careful about what they reveal. If Sun and Moon's pre-release period taught them anything (at least they seemed to learn from this with Sword and Shield), there is a such thing as revealing too much.
Well there's a difference between "big info reveals" and "not showing anything, at all"
In 2016, they had Sun and Moon.
In 2017, they had "We're making a Pokemon game for Switch!"
In 2018, they had Let's Go.
In 2019, they had Sword and Shield, and even revealed Nessa.
I mean, it's just a little longer of a wait, I'd think.
Going a little further.
2015 - technically had Super Mystery Dungeon but there also wasn't any mainline game that year, anyway
2014 - ORAS, specifically the first real trailer. As a reminder they had just revealed the titles (box art and artwork for the primals) like 2 weeks prior
2013 - XY
2012 - This one wasn't listed on Serebii so i had to track it down on a memory: the press conference actually did mention Pokemon BW2 though nothing was really
shown, per say, just the presentation did talk about it coming.
2011 didn't seem to have anything in particular, but I don't feel like digging through that presentation and such. I'll just assume no.
So the only time there was no pokemon presence whatsoever at e3 since 2011 was 2020 (due to the whole "there literally wasn't an e3 or even a june direct" thing) and...now, for seemingly no real reason. It is kind of a brow raiser; even if they do their own thing later in the month it seems like it'd have been easy to show off a little game play or throw them in a sizzle reel or even just reshow parts of the first trailers and a reminder of "and dont forget, you can get these classic games later this year!"
In the long run it's not a
big deal or anything, there will PROBABLY be a pokemon thing later this month, but it's odd to not have the bare minimum e3/nindir presence when this is one of their big tentpole titles.
