When can we see Arcanist / Summoner in action?

[Destain]

I have enjoyed the alpha videos however there is something I want to see more than the revamped Gridania and Black Shroud.

I would like to see where SE is at in developing the Arcanist class and maybe even a sneak peak at summoner AF in game. If they aren't that far yet I would settle for some video of Carby in action. Can it jump too? Is it an MP drain or does it have HP and a summon timer like the XI dragoon pet?
