Okay. GF will eviscerate anyone who leaks actual mons. I've seen the few who have gotten things TOO right, and haven't been smart enough to put a few fake things in to claim deniability. So here are some statements. Some are true, some are false.

1. Breeding is improved further, and shiny chance is increased with Shiny parentage, in addition to MM. Everstone passes down nature and ability 100%.

2.Pokeballs are transferrable. Have a spare ball, and you can switch a pokemon to it, or switch the balls of two pokemon. GF noticed balltism, and liked it. This works for all balls instead of Master and Cherish.

3.Mega Evolutions return, boosting mostly Gen 2 and Gen 5 pokemon. A single Sinnoh starter is given a Mega.

4.Hidden Power is selectable now, and boosted in damage.

5.Pokemon recieve stat boosts ala the gen 5 to gen 6 change. Abilities are changed as well.

6. 80ish pokemon. Second versions plan to introduce more, a design choice which is exacerbating worries in the company.
