Why would anyone be "concerned" because the majority of Ash's old Pokemon have been ignored? I thought it became apparent a while ago that the writers would focus on his Unova Pokemon, which haven't developed much and are in dire need of more attention. I mean when was it even implied that Ash would suddenly bring back several of his old Pokemon? Just because Charizard was featured on some merchandise and some posters? The best that guaranteed is that he's coming back, but that says nothing about Ash's Oak'd Pokemon.
