Look at that number again: 700. That's about how many Pokemon will exist once the new Pokemon games, Pokemon X & Pokemon Y, have been released into the wild. There will probably be a few more new Pokemon than even that unbelievably high number, depending on how far you're willing to travel in the game.
That means if you catch 5 new Pokemon a day, you could play the game for four months straight without catching 'em all.
And, as it's the first Pokemon game developed to take advantage of the Nintendo 3DS, you'll get to see all those Pokemon in full 3D.
The Pokemon X & Y release date is Saturday, October 12.
