Must nab the lot
If you want to catch Lation and Latias in Pokémon Omega Ruby and Alpha Sapphire, you're going to have to get an Eon ticket. And you can only get one of those by StreetPassing someone else who's got one.
That might sound impossible, but Nintendo has said that it's sending out tickets to members of the Pokémon community to get the ball rolling.
It suggests visiting tournaments and other fan events to up your chances of grabbing one of the tickets.
Once you've got one of the digital passes, you still need to head to Southern Island to actually nab one of the critters.
Pokémon Omega Ruby and Alpha Sapphire are out on November 21st in the US and November 28th in the UK. And if you want to catch 'em all, it looks like you're going to have to put some work in.
