Are you on the reservation list? Some of the feedback I heard from the HE show indicated that the people at the head of the reservation list line would start getting contacted within a week and a half or so after the show, and their units are supposed to be able to ship within a week to ten days after they are contacted. In fact, here's a quote from last week's newsletter ("this coming month" referring to May, since it was written in April):
An update for those on the Model 990 reservation list: The shipment is in sight, and we will absolutely begin shipments this coming month. Depending on a few last minute details, we expect to begin contacting the first of those on the reservation list with a confirmation/conversion message within a week or so after we return to the Hideout.
