Good, the biggest problems with BOTW can be fixed. Maybe the world will actually be full of stuff to do this time and combat will be rewarded.

I think this is interesting but it's also obvious the map is going to change. One of the most significant landmarks of the first game - Hyrule Castle - is ascending into the sky at the end of the trailer. It's a very obvious sign that while this is a world we've been to before, it's not going to be the world we know inside out - which is why that shot has us looking out from the Great Plateau. There are mysteries in the original game, like the Zonai Ruins and labyrinths, which remain unexplored - given the reveal trailer emphasises an underground space so much, I do wonder if that's going to be a feature of the map: substantial subterranean areas.

I don't think this is going to feel like DLC, but I do think it's going to be a much more direct sequel than we've ever had in Zelda before. It's going to pick up threads in a way a sequel like Majora's Mask simply didn't. That trailer hints we're going to get more of Link and Zelda's relationship - and likely more character development of Zelda as someone fascinated with the past and burdened by her duties. As I've suggested above, I think the Zelda team are going to take some of the mysteries they didn't explore in BotW and expand on them - especially the ancient civilizations. And, clearly, Ganondorf is likely a significant feature of this game. Calamity Ganon is seen as a force of nature and a primal, metaphysical being more than anything , and the history of the man he was has clearly been lost. The Gerudo have tales he may once have been of their tribe, and the Zora histories don't connect the "evil man with designs on ruling the world" with Calamity Ganon.

So the core relationship of the series - between Link, Zelda and Ganondorf - is only implicitly explored in Breath of the Wild, but could well be a key focus in this new game. being set in the same 'world' doesn't just mean the physical landscape we've explored - which I expect is going to significantly alter in some way - it means also being grounded in the narrative tropes and themes that BotW hinted at, but didn't fully explore. I'm not sure why this is a huge cause for concern - this game has been in development for around 18 months and has at least 16 months of development left, in all likelihood. On top of that, plenty of other art forms and mediums of entertainment aren't afraid to re-use locations and worlds and relationships by expanding on them in sequels.

EDIT: I'd also point out after E3 2016 that people were claiming Breath of the Wild would feature no towns and would be terrible as a result. We've seen one minute of footage (which I do think hints at some key ideas for this game, hence being used as the reveal) and has some cryptic statements from the developers. Let's not lose our heads.

In short, it's just a freaking DLC sold at full price. I thought everybody got that immediatly.

Well, no thanks. I'm waiting for a real new Zelda, hopefully better than BOTW.

I really want to revisit that world again. And that means new story and and enemies and all. I am sure they will deliver on all fronts again, and make it as exciting as the first game. I'm sure we will get something at the VGA's and then we have more to go on.

So a Q4 2020 release is a possibility? This might mean that. Honestly adding dungeons, new gameplay elements and improving the UI/UX would be enough for me to try it out.

I know right?

And honestly there is so much untapped potential and ways this can be handled, it could honestly feel like an entirely new map while also being the same (if that makes any sense).

I am suprised at how many people jump to this just being a full priced DLC.  But then, a few people may just be looking for ways to downplay the game too.

While it is a legitimate concern if we had a gameplay trailer and it looked like the same game, we know next to nothing about the direction they are taking other than it will take place in Hyrule and it will be very dark.  So with that in mind, I think people worried need to take a step back and just be happy for the announcement.  I am sure we will know more about the game soon enough and we should reserve judgment until then.

For now, I just like to read fun theories about the breakdown of the trailer because that is really all we can do at this point.

Curl... It’s going to be good. No worries.

So, they will maintain the original landscape, I see no problem with that. Everything can be changed; new cities, new structures, new vegetation, new animals, new monsters, new caves and even new areas can be added to the map.

The nintendo side: fake news, moral panic, misinformation is the norm. The worse the unfounded news is better the acceptance.

Nintendo aways doomed and make negative shits, aways. Microsoft and Sony never wrong. Nintendo aways and doomed.

1. Hyrule Castle is being raised, maybe other structures get raised too like the towers did in BotW 1.

2. They found Ganondorf underground in an ancient dungeon like place. Who's to say we may have more of those. So tons of underground hyrule.

3. Hyrule Castle is being raised, maybe we visit Skyloft and other places in the sky?

4. Maybe its been a few years since BotW finished and thus many new towns, ruins fixed, Lon Lon ranch rebuilt, ect. The world could look insanely different being not broken. Remember, enemies spread throughout the world, closest to hyrule town kept all civs like spread out to the edges. 

5. Think of OoT and the difference between adult and young Link's hyrule. Same overworld, yet very different. 

6. 90% of all Zelda games take place in the same Hyrule. Always going to Zora's domain, death mountain, gerudu's desert, ect. All in same locations. Does it looking somewhat different in each game really make it feel so much more special? I'm more of a different mind many times. I'm like comparing Zora's domain in each game and like "how does it look so insanely different each time" Not that things can't change, but sometimes the locations seem almost different or there is no evidence of what it used to be.

7. I feel like will not have his rune abilities he had in BotW, thus even if exactly the same world it will feel totally different traversing it.
