I go to the Lamley Group page again and the first post I see is a new HW model for 2015, the Lamborghini Urus.
This model looks pretty good, too. There's pretty good quality headlight tampos, slight exhaust detail, and an Urus plate on the rear, along with Lamborghini badging front and rear.
No confirmation on how early these will appear in a 2015 batch, but considering it's unveiled now, I'll bet it's on pegs by or before 2015 Batch C.
