I replaced Pokemon_(game)tag with Pokemon_(anime) - for now Magiana was confirmed only for a next movie, there's no info about her in-game debut. Okay - for some reason i can't delete pokemon_(game) tag, but it should not be here IMHO.
Nope, it's just some rumors from retarded people that like to scream GEN VII CONFIRMED!!11 for not reason. Considering how she will be a major plot point in next movie, i think that she will be in Pokemon Z (or whatever they will name "that third" game), or hec - she can be event 'mon in ORAS.
