The upcoming games are bringing a brand "New Type Of Evolution".
The Pokémon announced to be evolving this way is Pancham[into Pangoro]. So from the little details we have lets speculate the way of evolution. Let's start it!

My Opinion: The Pokémon might be evolving only when it is fainted by a stronger opponent after crossing a level. In case of Pancham it might be after level 25.
