In regards to the many different things going on in this thread ...
There is supposed to be an "unconfirmed rumor" about an upcoming expansion currently entitled Extinct Animals. The official forums at Microsoft Zoo Tycoon Forums contains much more information. The "unconfirmed rumor" is the official stance taken by the moderator at that forum, who is not an employee of Blue Fang but who receives information and posts official notices as requsted.
However, there is nearly incontrovertible evidence that the next expansion is, indeed, going to be the Extinct Animals Expansion Pack for ZT2. There's a Microsoft Press Release which includes the Extinct Animals XP as one of its Games for 2007; and even more compelling is the video clip shown at the Consumer Electronics Show (the largest consumer electronics show in the world) which was subsequently reposted on the most popular gaming news websites. So, eh, while their "official stance" may be that it's a rumor, everything else is pointing to a real expansion that's looking pretty good.
Also, there's no reason to request, criticize, or even compliment the presence (or lack) of BF's representative. If they considered it vitally important for him to show up, he would. Maybe he just reads the forums without writing. Maybe he doesn't read the forums at all. He'll show up when he needs to show up; there's certainly no requirement for him to show up at all.
