Well, everything that we have is just a post provided by MHCaboose, let me copypaste here:

We have a clear view of this new Axe here and can see that it's still using the same Phials that the Switch Axe does, but instead of sending the power in a steady stream to the blade, it uses the Phial to super charge the blade for certain attacks and can use phials bursts for movement instead of a direct attack. Due to this the Axe itself is a lot more bulky than that of a Switch Axe and is actually mainly held from the back with an extra handle, the trigger being inside the main handle still.

Accel Axe can use its special Phial system to launch hunters at speeds across the ground or up into the air, and attacks performed will be based on how close you are to the monster. It has 3 main special moves, the 1st is a charged dash called "Acceleration Force" which will allow the hunter to run faster than with any other weapon to quickly close distance or make a quick escape. The 2nd is called "Jump Force", this allows hunters to attack while airborne after blasting themselves upwards. The 3rd is called "Burst Slash" which is a special charge attack, dealing a succession of both quick and powerful strikes. So this Accel Axe (accel being short for accelerator) is like how Valphalk is a bird with jets on it, this is an Axe with jet boosters on it.
