I was curious to see if Feral Interactive would be porting their existing library to Apple silicon, so I emailed them a couple days ago. Here's the reply:
"Thanks for your email, and apologies for the delay in reply as we asked our team for accurate information.
We do not have access to new Apple hardware before the street date, so have not yet tested any games on the new Macs. Rosetta 2 (included in macOS Big Sur) allows apps developed for older Intel-based Macs to run on the new Apple hardware. We expect our games to play without issue using Rosetta 2, and so there is currently no plan to update them to run natively on non-Intel Macs. If a game has an issue we will of course investigate.
We plan for all new releases to offer native support for both new Apple hardware and older Intel-based Macs. Our goal is to accommodate all Mac gamers whatever the chipset of their Apple computer."
Unfortunately, it seems like they have no current plans to port their existing games to ASi. However, they did mention new releases would be supporting them. I'm unsure about other devlopers/porting houses, but I expect largely the same response. At least we have BG3 confirmed.
