Uh... no. We had full control once we recruited them. We had to follow the game mechanics and rules, but I could dualclass Imoen into a mage for example if I wanted.
Following BG2 Imoen was kind of a mage anyway.
I think the major problem about this discussion might be, that we don't know the mechanics yet. That being said we can only assume, that the controll we'll be given should be as much, or not as much as BG/IWD/PST. In BG much of the controll (e.g. multiclassing) was predetermined by D&D rules and so people couldn't totally mess up the characters personality by their own choices.
But since the mechanics aren't out yet, I really would prefer the "cautious" way of controll.
Probably we will reach the 2,6 stretch goal anyway, that's just statistics ...
So if one of the NPCs doesn't fit the way you want him to be, you can still make that single exchance in your party!
