So you looked at SMG sales and being that it peaked at ~ 1 million in Japan, that it doesn't have legs anymore and Wii sales would then plateau.
Then when we looked at MGS2 Sales in Japan, where that figure peaked at ~ 1 million (for all intents and purposes), and you respond with DIFFERENT REGIONS, DIFFERENT TASTES.
Do well its either one way or another, isn't it? =))
