Miniature giant space hamsters? Yes. Cute rabbits? No.

I find it odd that people are disregarding a lot of the funny moments in the original BG games. Remember when you got the Nether Scroll for Edwin, and he accidentally changed his gender? The party took to calling him Edwina...yeah, everything in BG is super serious...

Not only that, we have only seen 1-2 hours of gameplay and haven't even been to a major city yet. I'm sure we will be exploring the seedy underbelly of Baldur's Gate itself (not to mention graveyards, crypts, etc.).

And just because Baldur's Gate 3 can stand on its own doesn't mean it won't have the story elements to tie in this game with the previous two. The Cult of the Dead Three is an easy way to connect the events of the Bhaal Spawn to the current game. BG2 had Mind Flayers beneath Athkatla trying to organize, and you find a letter stating:

"The base is established, and the infiltration continues. The Hidden gathers followers, and soon we shall dominate the minds of the entire..."

It is quite possible Larian is using The Hidden as a jumping off point. We won't know until more of the story is released.
