I would like to see new evolutions to pair up with Eevee's seemingingly interchangable genetic system, so far lots of the main types have been used for its evolutions such as Water, Fire, Electric, Dark and Psychic... But what about Grass, Fighting, Steel..or possibly a secondary stage after the initial Vaporeon, Flareon, Jolteon, Umbreon and Espeon lines?
But back on topic here, I'd want to see a Magmar evolution, right now it just looks too ugly, same with Electabuzz in my opinion so I really liked what they did with Elekible..And with the Chancey Prevo, it makes sense to me. I mean think about it..has the people who HATE Chancey getting a prevo thought about where Chancey's come from? Chancey's HAVE an egg in their little sack-pouch thing...and so that egg could be in fact the prevo of Chancey itself, just not elaborated on until now, since we have a factual representation of what could be the egg. So there, hah, I now see a reason for a Chancey Prevo.
