I really really hate to think this out loud, but I have little faith in what the agent said. I'm reasonably sure most agents don't really know much about even their current devices, I sincerely doubt that some low or even mid-level agent can randomly bust out something like "oh yeah we're getting the HD2, it'll be called Adonis. watch for it around Christmas". Just doesn't sound feasible to me.
IF this particular agent does happen to know something about some upcoming phone, they could easily be confusing that other phone with the HD2.
All that said, I would like nothing more than to be wrong about everything I just said
