Why are people so worried about ruby and saphires remakes? Let me remind you people that Sakurai puts pokemon characters based on his current popularity, Sceptile isn't anywhere near as close as mewtwo in terms of popularity, blaziken is the only 3rd gen pkmn that can compare to him and he is unlikely, mewtwo chances are still very good, I'd say 85% at the least, Also, let me remind you people that mewtwo is set to appear in the next pkmn movie which will be released in July, close to smash bros 3ds date, I'd give sceptile a 25% and blaziken a 30%, let's not even talk about swampert
