They have to leave something special for the third game... and especially for those people who bought all three games. I've heard of the combined map for owners of games 1 & 2, but I'm sure they'll have an ace up their sleeve for the third installment. That makes sense. Although who will be left for the third game then? Most of the interesting races are already a part of games 1 or 2. Tomb Kings are probably the most interesting of the unconfirmed/remaining races.
