Hey, I have a question. Anyone knows how and if a Pokemon who levels using the Pokewalker will earn EVs?
Earning EV points on its own without training, more than likely not. However, I'm sure that if you have fully EV'd your Pokémon of choice and transfer it to the PokéWalker, then it should gain the correct EV's while being leveled up. I'm not 100% sure, but with the gathered information collected, I'm pretty sure this would be right.
The pedometer like I once stated before, whether some people may find it unecessary or not, will still be a useful addition to the games. Because of the opportunity to collect items, Pokémon, and grow levels in an easier way, people who are lazy to train within the game can simply use the 'Walker and gain exercise all at the same time while leveling up. Not to forget, the famous Jirachi event is in need of the PokéWalker, so it'll be of some importance to the players.
