Beldum and unlike Zoroark . Plus the writers writing the series at faster pace isn't going magically make game freak to be willing to reveal their pokemon at an earlier stage of development. It only has been a couple years since gen V. The anime has a thing for unevolved pokemon so I think it's a stretch to say its asking to be evolved. And I doubt they will release less than two eevee evo's at a time and he only one Eevee. Eevee's here to advertise BW2.
