The facebook page for Maxsoft, an electronics distributor in South East Asia has posted this blurb for a Pikachu distribution at an Isetan department store in Singapore, during the "Pika Pika Carnival."
The event runs from May 11th to the 20th.
Interestingly, it will be obtainable on Japanese games AS WELL as English games.
It appears to be a repeat of the Strongest Pikachu event, based on the moveset and hold item.
