A little bit of an odd question. I want to know how many Pokemon from the generation 5 Pokedex were revealed before the games' release. I want to see how much was revealed compared to the amount of new Pokemon overall in the generation.
If I counted right, 70 Pokémon were leaked before the release. In comparison, that's just a little over how much Kalos mons there are.
Source: I scoured through the DB's oooooold pages and counted.
