It Appears the Hive Tyrant model as it currently exist is Dead. just a couple weeks ago they move it form Trade to Direct and now I get an email that states:
"We are currently packing the order you placed with Games Workshop. However; one or more of the items you ordered have been discontinued and are no longer available.
The item(s) are:
99810106007
Tyranid Hive Tyrant

99060112043
Dark Eldar Haemonculus 1
OBSOLETE
99060112044

"
So i guess this means the Hive Tyrant is going all Plastic or a Mix kit to make one of the unmade Bug Models or full Finecast
