I could totally see the 3DS being the best-selling console in August. Amazon has it placing very high in most of Europe, and completely sold out in UK/US, so it itself is doing well. Currently selling more than the PS4 in Japan. Xbox price cut will hurt PS4 sales in the rest of the world.
Bet with PeH:
I win if Arms sells over 700 000 units worldwide by the end of 2017.
Bet with WagnerPaiva:
I win if Emmanuel Macron wins the french presidential election May 7th 2017.
