Wave Serpent/Falcon Double Kit?

Hi, guys. I want to ask you a very important question. I want to buy a Falcon grav-tank for my army, but I can't find it anywhere. (even on GW website!) Is Falcon now a double kit with Wave Serpent, like it is with Fire Prism and Night Spinner?

It's a separate box.  I know it's on the web site.

It's been a while since I built mine but I believe there are 2 sprues. The Falcon and Wave Serpent share one of them but the other is different.
