All of this speculating is really getting me thinking. I'm not sure if anything like this has been said because i got to page 3 before i decided to write this(you cant expect to read all 76..).
Reshiram- Fire is very powerful, but it is also hard to control. It brings life and destruction, black and white. We depend on fire but it is also human instinct to fear it. Fire is not very controllable, it leaves permanent scars of destruction. It is ancient technology
Zekrom- Electricity is modern and controllable. We depend on it in every day survival, but if it was gone it would be very hard to live, black and white. It's used in circuits that are created by man and controlled easily.
I think that neither legend represents yin or yang, but they both represent yin and yang on their own.
Now that I'm done with that, speculation time :D
- Pokémon Grey/Gray Version
- Storyline will stay pretty much the same except for the legends
- New cities/towns
- Able to reface the gym leaders (The first gym will then become a triple battle, and the last gym will become a double battle)
- The Pokémon musical have more to do than just dressing up your Pokémon
- Mascot will be Kyurem
- More triple/rotation battles (I'm thinking in the battle frontier)
- Battle frontier
- New formes (Cofagrigus, Zoroark, Emolga, Cryogonal, Volcarona, etc.)
- Able to get all of the apes
- Hints leading to a remake of either Hoenn or Kanto
I'm not sure if a lot of this has been posted already. As I said, I'm not reading 76 pages... But yeah that's about all I have to say :)
