I think I read somewhere that the point of the Barcelona studio is to port their games and updates to other systems, thereby freeing up resources and manpower. Since one of the main studios doesn't have to work on that, they can focus on the development for the game which means that once everything gets into a flow, I posit updates will come out faster and with more changes/content. Porting can really slow things down sometimes.
That said, it does explain why there has been, well, radio silence on what is going on since opening a new studio is likely a logistical nightmare, but in the long-run, not just for beyond BG3 but likely for BG3 as well, I think this will turn out to be something good, or at least I hope it will.
Or it could be a total over-reach and they've gotten ahead of themselves - wouldn't be the first time a company has gone bankrupt by expanding too fast and purchasing costly assets.
