Boss Battle Ziggs Splash hints at Boss Battle Cho'Gath?

Something stood out to me when I was looking at all the little Easter egg tie-ins for the other themed skins. Sona, Ahri, Blitzcrank, Corki, Brand, etc. The knocked over machine people say is for Malzahar, but I don't think so. I think it is Cho'Gath.

If you take a real close look at Malzahar's head from his Boss Battle Splash and compare it to the machine image, there are some differences.

Malzahar Splash: Green Diamond Formation of forehead is 4 segments: 3 green, 1 metallic. The 'V' formation on helm is blue and then golden. Malzahar has no spike protrusions. Malzahar has no claw arms coming from behind. Malzahar's voidlings are sharp diamond-esque shapes.

Ziggs Splash: Green Diamond Formation is solid and fully green. The 'V' formation on helm is solid silver and is continuous. The head has two claws/spikes. One on each side. (Who else in league has such features? Cho'Gath) Look closely beside the head and you'll see two (oddly smooth) shapes. Similar to Cho'gath's rear arms. The claw coming through the screen. Not similar to a Voidling leg.

I believe it is a teaser for a future Boss Battle Cho'Gath skin. Thoughts?
