Yes. New way besides the Masuda Method.
In B&W2, there's an item called the Shining Charm that allows higher Shiny chance. The chance of WIld Pokemon that are Shiny goes up 300%. It works with Masuda Method as well. That 1/8192 chance is no more! :D
This Key Item increases the likelihood that you will encounter Shiny Pokémon. When you have the item in your bag, then the chances of encountering Shiny Pokémon in the wild is increased to 300% of normal, making it a 1 in 2,370.6 chance. If, however, you're using the Masuda Method to breed, it reduces it from 1 in 1,365.3 down to 1 in 1024.
You get the item after catching all Pokemon in the National Dex. You receive it from Professor Juniper.
