Only Zelda?
If they hold a digital event or Nintendo direct during E3 that doesn't really count as being a part of E3 does it?
Forgive me if this isn't completely accurate but from what I understand, Nintendo announced their E3 plans. They said they would have Zelda Wii U playable at the convention, and they would have a streaming of the demo on the first day of the event. That's all they said. Since they didn't mention having a digital event, people are taking this to mean there will not be one.
Maybe they will have some sort of Direct around that time, but for now I think everyone's best bet is to not expect anything Pokémon-related during E3. I'd go so far as to not expect anything other than Zelda Wii U/NX during E3, actually.
I might be being a bit too optimistic but I do think it's safe to get excited this time around. They're going to have to show us gameplay/starters/legends eventually :c
Well I think a good chunk of the pessimism is actually just jest, playing off the "CoroCoro 'news'" we had been expecting but didn't get.
Although I can understand where the real pessimism is coming from to an extent. Mascots are certainly "big news," but that could very well be all they show--and not even in-game footage of them, either. And after waiting months for any sort of information at all, it could really seem like a let-down to some people. It would certainly disappoint me, because then I'd be wondering if they have any sort of major information to reveal at all, or if all they have are the 20 new Pokémon of this gen and no new or returning features to show off.
And yeah, they have to show us information eventually, but then again, for X & Y they didn't reveal the starters' final evolutions until the day of the games' release... With that in mind, "eventually" can be "after the games are out," which is fine in some ways (I like discovering stuff for myself while I play so it's not like I want them to show us
everything), but...not-so-fine in others (some people base their starter choice over the final evolutions, why did you wait until the game was already in peoples' hands to show their Types and what they looked like?!).
