+1 on this. The fact that there seems to be eight confirmed companions, paired with their earlier statement that we'll need to commit to a party at the end of Act I (don't know if this has changed or not yet) makes a 4-man party (meaining, only 3 of these companions at most once you factor in mercenary characters) seem really limiting. Plus, if it works similarly to how it was done in Divinity: Original Sin II, it means we may need to do three separate playthroughs to see the stories of each of the eight companions.
