ARRRGH, DO NOT TOY WITH MY EMOTIONS LIKE THIS!!!
Seriously though, I think Larian could/would do a great job with a Baldur's Gate 3, although I assume they'd go turn based instead of RTWP.
I loved BG2; it's easily one of, if not my favorite game of all time and thought BG1 was pretty good, but I'd be hard pressed to say they weren't full of design flaws and bugs, even after all the patches. Community patches/mods made those games the legends they are today. Larian could easily knock BG3 out of the park, if they actually bothered to go through the trouble of getting the licenses sorted out.
*EDIT* CJ_Parker mentioned Obsidian doing BG3 theoretically; I think they'd do a hard pass if it was even offered. They went with all original IPs a long time ago for a reason, and I doubt they'd want to get back into any further control from WotC or anybody else. On top of that, I think they're a little burned out on team based isometric RPGs for awhile, hence that FPS game they're making, Outlands or whatever?
Not that I wouldn't love Obsidian doing BG3, I just don't think they have any desire to.
