I don't have inside knowledge but have followed Bioware (given how many of their games live rent free in my head)
1 - 2017 they cut from 500 -> ~350
2 - 2023 went from 350 -> 200 that included a bunch of very senior people including the OG writer of Baldur's gate Lukas Kristjanson
3 - Early '24 cut down to 100 skeleton crew as the writing on the wall for DA Veilguard sales materialized (sold about 1.5m vs 3m projected)
Note that the 1.5m number given for Veilguard was for the vague term "engagements" rather than sales, so there's additional padding going into that figure.
And veilguard was an abomination of corporate groupthink based on some perceived cultural zeitgeist. I couldn't finish it the dialogue was so painfully cringe.
