I would agree if not for the fact 3DS released in all other regions 1 month after the japan launch and is 2 months after the japan launch for vita so 3DS will have a month more of sales in NA EU and AUS

You can correct for that in "launch-aligned" that is by combining the first three months of each region to get the total first three months without having to worry about such matters
