Definitely a concern of mine that it could be BoTW 2. A big part of the appeal of the game was the exploration. Going through the same map would be a big downer.
But they've been tight lipped for a reason. We already know that they've vertically added to the world, those sky bits look intriguing. I suspect they have changed the world enough to overcome this issue, or at least hope so.
We've seen some pretty games on the Switch. BoTW being a Wii U game initially would have effected development. I'm sure they will get Tears of the Kingdom running better
Here's my guess: the 'tears of the kingdom' is a double-meaning, and refers to some cataclysm that 'tore' Hyrule apart, with huge chunks ending up in the sky. If you look at the map when he falls in the trailer, you can see some big holes taken out of the map, such as right here. So it will be the same Hyrule map, but it's going to be significantly altered. The first trailer also showed some underground bits, so perhaps there will also be more cave exploration as well.
I think the 'tears' can also refer to the tears of light in Skyward Sword, which is indicated in one of the drawings in the beginning of the trailer.
