256 pokemon. But all together 493.
Yes, all 493 pokémon can follow you.
there arnt any new Pokemon but you can catch all 493 Pokemon
No you can not get all 493 Pokemon in just that game... if you want to get all 493 you have to get migrate some of the Pokemon from the previous games like pearl, platinum, emerald and so on... ( not including the GB color games). Some Pokemon, like arceus and celibi, you'll have to go to events in order to get them. For Mew and manaphy you have to get Pokemon ranch (if you have a wii, if you don't... your out of luck) Yes their sprites look different ^-^
