As far as I know, generation 5 will include the following:
- Three starter Pokemon (Water, Fire, Grass) will be available as the players first Pokemon.
- A rodent normal type and a bird flying/normal that annoy you to no end.
- A handful of version exclusive Pokemon, including the duo that will represent the versions.
- A 10 year old boy or loli will be available at the beginning.
- A professor that doesn't know your gender or name.
- A villainous team with 80's hair.
- 8 gym leaders (I hope for a Dark type gym leader).
- Zubat, Geodude, Magikarp, Goldeen, Abra etc.
