I hope and think we will get a grass starter and it will be Sceptile. I'd be glad about them taking out the Pokemon Trainer with a trio of starters and giving the 3 starters their own slot. To me, Brawls Pokemon Trainer felt like a concept consisting of 3 Characters Classes that should have been kept separate playable characters all shoved down into 1 transforming character. I think that it is quite possible that we may end up with 7 Playable Pokemon too (Sceptile 5th slot, Jigglypuff 6th slot, Mewtwo 7th slot) considering the following information:
We had 6 Pokemon in Brawl!
We were originally going to get 8/9 Pokemon for Brawl making 7 here quite possible consisting of what we got +
