I have no problem with all these evolutiosn being added. If anything, it's good. Helps get underused Pokemon back into the game. With Mr. Mime's filter ability I can see him being used much more now. Electabuzz has had a surge in popularity due to Elekibble (or Eleking as I reckon he'll be called).
But then, there are soem stupid mistakes. PorygonZ has worse stats than Porygon2, wtf? Buuburn (Magmar evo) looks like a fat... ball. And they removed the Magmar's line defining beak, wtf? And who ever came up with how Lickitung evolves must've been a right idiot.
So quit your complaning about this gen. Overall, they did a good job fixing some bad lines. They needed to do it eventually.
On topic: They'll just keep going. Nintendo's goign to be around for a LONG time and so will Pokemon.
