if the last guardian has those trailers i don't see why would Nintendo could put another 30 second trailer for the game. No big surprise and we all know their E3 isn't good. the games are good but the E3 presentation was really not good and it really deflates a lot of hype for several people.
it is also true that Nintendo mentioned they wanted to show only games coming in 6-8 months. but they've also shown games more than 8 months last year. so why change in direction which is why a lot of nintendo gamers are confused and disappointed. anyway it is over, stay positive. good for splatoon getting that 1 million sold. and i've checked most of the Nintendo games on treehouse and several of them aren't that bad. and checking podcasts and see if there were interviews with the developers like Metroid Prime: Federation Force, the presentation isn't good but the developer mentioned about the gameplay more which wasn't shown in E3. it seems just an game that was really not polished for even a demo.
going back, it really just disappoint the Zelda userbase and waiting for the Wii U game.
