In the yoshi-P interview on the IGN channel on youtube, he mentions that you should "look forward" to Gigamesh gaining more arms. I assume he is saying to look forward to extreme mode. That would be a pretty obvious nod if that is true.

Maybe when we get the next primal... oh... "whatshisname"... the guy with the awesome beard! At that time, I'd bet we might see Gilgamesh EX as well, or soon after. It wouldn't be stretching the imagination that much.

What do you think Gilgamesh Ex will drop though? The obvious thing would be weapons but Levia Ex has that covered... so, I'm at a loss on that question.
