If they didn't change the chainchomp and goombas to Zelda monsters that served the same function I doubt we'll see anything beyond streamlining alterations.
You're making the hidden argument that Mario references in Link's Awakening are inherently bad and if Nintendo decided to significantly alter the game, they would get rid of those references first and foremost, ergo there won't be significant changes because we're still seeing the goombas and chain chomps in trailers.
Am I getting this right, because I really didn't think there'd be anyone who considers those easter eggs anywhere close to bugs or undesirables.
This is the first time they remade a pre-OoT game on a home console, even though the switch kinda blurs lines there.
With A Link Between Worlds, they set out to recreate ALttP but quickly decided to make a new game out of the assets instead.
Now they're going to use the most powerful hardware they've ever had to recreate one of the shortest and oldest Zelda games out there, and retailers are already (speculatively?) pricing it at 60 bucks.
I just really have a hard time imagining it'll be a pure remake if even the Gameboy Color remake at least had a new color dungeon.
