The last time we had three titles in a Pokemon game was when there was Pokemon Crystal, Emerald and Platinum. Pokemon Z could be about to repeat this in Kalos.
We have not heard anything from Nintendo but fans think that Pokemon Z is being made. Due to the speculation and rumours fans have been talking about what they would like to see.
1. Even more mega evolutions
2. More tutors in the game
3. The option to change the difficulty level before the game
4. A good reason to level up Pokemon to 100
5. The shopping plaza that was in Pokemon Black and White 2
6. The VS Seeker tool
7. More legendary Pokemon stories and new ways of catching them
8. A Pokemon contest such as the one in Pokemon Ruby, Sapphire and Emerald
9. A storyline that justifies completing the Pokedex along with breeding Pokemon
All of these are superb ideas, but it could be that we will never see Nintendo release Pokemon Z. Nintendo could in fact go down the DLC route instead.
