That still doesn't make it Mega Evolution. Houndour looks a lot like a half developed Houndoom, and Igglybuff is just a smaller Jigglypuff. Pokemon have evolved into visually similar things before.

I'm not saying you can't have a fourth evolution, just that you can't say 'oh, it's like Mega Evolution but not' because it very clearly is nothing like Mega Evolution.
