yeah they were clear that the biomes shown at minecon were it. The basalt deltas weren't actually planned back then but because they left it kind of open ended a lot of people expected another biome so they made the basalt deltas a thing. also you're right maybe the entire area below y=0 shouldn't just be deep dark. Maybe it spawns in large patches but there could also be some areas where caves just extend all the way to bedrock. Also even though there's only like 3 or 4 cave biomes the are adding integration to the above ground, like a jungle that has a cave opening will have a bunch of vines and grass at the opening area of the cave, and they are going to update the caves as well further down the line. It may be a few years but now that it's not a whole overhaul of the system what's stopping them from doing what they did in 1.7 with the overworld someday and just add a ton of new cave biomes?
