Matt implied that Sparky not returning was a higher decision, I believe it was orders from Nickelodeon, and not Butch Hartman. He said clearly they "decided to not have Sparky back". The episodes are produced months in advance, and voice acting takes place even before the animation. They are probably way deep into production right now, if Sparky would return, the voice actor would already know that.

But anyway, we never know. He may come back for one of the last episodes in the season. But I wouldn't be optimistic about it.
