Since Wendy got Feathers and all, we can expect Gajeel to also grow some unique attributes. Maybe a Cyborg-ish look? I don't know, as long as it doesn't look like Iron Dragon's scales.

And Natsu I expect to surpass both of them and master it! Though I doubt that will happen in this arc. But who knows. Maybe he needs to undergo the same procedure Zeref used on Acnologia in order to finally beat the both of them. :/
