Aren't the sky islands, totaled together, somewhat equivalent in size to Hyrule from the first game? I mean, check out the scene of Link falling from the most recent gameplay demonstration, they're everywhere. Not to mention that there's bound to be some very real, tangible changes to Hyrule itself, and the new will most likely total up to about as much content as the first game. That's not even mentioning how the new abilities provide so many new ways of interacting with the environment. Should the game have come out sooner? Yes. But since Nintendo seems to be one of the few major studios that doesn't have a track record of crunching their devs, and with how hard COVID seemed to have hit the team, I'd rather be getting it in a complete state now than a broken mess a year or so ago.
