I don't think they would advertise Scribe and not give you the pen. Besides, the pen is in the pictures.
I'm completely with you, seems crazy that it wouldn't have the pen, it is shown in only one picture (alternate view #3), but directly from the Best Buy Page:

Note it also says that it notifies you of incoming calls and messages. Implying that it's a phone. I know that the Galaxy Tab 7" has phone capabilities in markets outside the US, the Flyer probably does too, so this is hopefully just a case of cut and paste from the generic information that HTC sent out.
