No probably not since they like never go to the final forms in the main characters party, cept for ash's Charizard. Plus i think Grovlye and Combusken are supposed to stay at the same stage, and i don' really think that Grovyle'l evolve.
but hey who can tell? It's just htat that season is almost over. D/P'll start soon and they won't have it evolve then.
Arcanine out.
