Although I don't watch the anime, I am very curious to see whether they make pikachu into a fairy type pokemon similar to marill. This would be curious as on one hand they are heralding the new type by retyping arguably the face of pokemon, while on the other hand they are destroying the tried and true partner of Ash.
My only real problem with fairy type is the obscurity that has been discussed. I am sure this will be settled in time and GF will come up with a quasi logical system for retyping and typing things fairy type but until more is revealed how far does it go? Marill, Pikachu, Plusle, Minun, etc all appear to have the same claim to fairy type the cute adorable pokemon. Surely not all cute pokemon are fairies. Gardevoir is an interesting choice to illustrate that fairies are not merely cute chibi pokemon, but can be fully grown and powerful. I am excited to see fairy combos that will allow GF to lead the fairy name away from cute and tiny and show some darker full developed fairies.
A pseudo legendary will probably be fairy to show off the new type. Although so far this gen appears at least mostly from the rumors attempting to play around with mixed typing far more heavily than Gen 5 did, which I greatly appreciate. So possibly the majority of other types lacking a pseudo legendary may have the opportunity to join the fray.
I will lose it if IVs become manageable based on the pokemon amie. Hopefully, eying and IVing being visible in the game and made easier will allow for trainer's pokemon to also have some evs as well as a better AI. This would make the game harder which a lot of fans have been asking for. Many will argue that Pokemon is a childs game but nintendo acknowledges the large player base that has stuck with Pokemon growing up which has sparked many of the innovations that we have already seen. If this or any harder mode exists I also hope that it is available from the get go with as the key system in BW2 was a hassle and annoying imo. If they want to continue that method maybe a possible nightmare mode could be available after finishing the game. In this mode all trainer's pokemon will be higher leveled, better move sets, and EVd. Possibly asking too much but I can dream.
Also despite the graphics, beautiful battles, I really hope that the story for the game is well thought out. I greatly enjoyed BW for their story. Granted I acknowledge that I will never receive an open world allowing me to explore and take on the gyms in various order or where decisions I make affect the story to greatly, but little add ons beyond oh no one has seen pokemon before please collect them all or battle the gyms and become champion would make the play through that much more enjoyable.
I am for the first time since gen 3 interested in poke contests. I love the simplicity of gen 3 contests. I found gen 4 and 5 contests tedious and a waste of time. With the new frontier on the 3DS as well as the 3D, I am excited to have a more visually entertaining contest experience.
I realize that I am starting to ramble but as I mentioned the increased dual typing as well as the stated interested in competitive battling makes me curious of the trolltastic spreads that the pokemon will have this generation as well as the possibility of making amends to spreads of pokemon of previous generations. As a competitive battler I would hate to see spreads changed as it would create and upheaval that I simply am not ready for. As a fan of several NU's I would love to see some slight boosts. I in no way intend to start the arguments that derive from this, I am merely pointing out that they are changing types of old pokemon and thus changing stats has a slim chance of being possible.
