If you want the Vortex Apocalypse template and can't find it... Check out GW UK's online store. I just ordered one for myself for here in the US. Sure it costs a little more but it is wicked cool looking vs mundane 3" Blast Template...
Also for you Kitbasher/Kunverzon People out there.... the GW store site has sprue pictures for most of the Warhammer/Warhammer40K line online. Don't need the complete catalog as much....

It appears that the Vortex template is limited release OUTSIDE of the UK only BTW!
