Forge theory: The buster blade was a prototype

What makes me think of this is that every ability that was meant for Forge was given for the buster blade so it makes sense that they were testing His abilities and they were using the sword as a prototype for that. Charging forward, Blocking, doing an uppercut and slam into the ground all were leaked abilities for Forge. My guess is they are planning to release him as a surprise and probably in a big update (Apex 2.0 maybe?).
