I#ll reserve judgement until later... really, if you think about the original floater, he was kind of a lame enemy. his "floating" didn't give him that much of an advantage, and in the new XCOM, which is a lot more dynamic, anything closer to the original would have been way too much of a sitting duck.
this one sounds to me like someone read the ufopaedia text and inferred that the surgical altering described there makes him a cousin of the Bio-Drone - an organism that has been forcefully fused with a machine and that is now a strong and utterly mad beast. yes, it deviates quite a lot from the original, but I don't know if that's a bad thing. If you want to play the original, stick with openxcom
