@Darksnow - this is answered now in the new rule book.
pg 7
- player may not have more than 7 cards in their hand at the end of their
turn unless a recruited character allows for more. Players must discard
down to their hand limit before the end of their turn.

Lots of Assets and Rules Updated

I have a question, whats the max amount of cards in hand? I see that at least one card allows you to keep an additional card in hand but I didn't see in the rules what is the max hand size.
