Thanks for responses so far. Looks to me (with additional input) like 360 managed a very respectable performance then (not just compared to itself).
I know the near 300% bump, etc. is great but it was still only to 24K units which is pretty small compared to Wii.
What I wanted to understand whether the SW was good and it seems it was reasonable for this type of game in Japan - so it seems Japanese will definitely buy 360 based titles in reasonable numbers. If the HW bump doesn't last long or raise the average weekly level though I think that this is just another Ace Combat in terms of really helping 360 HW in Japanese market.
Like I said those kudos to MS for going for the titles/genres that will give it the best chance.
As a developer though I wouldn't go 360 only unless MS was paying for the privilege as the evidence sseems to show you'd be better multi in Japan for sure right now.
Try to be reasonable... its easier than you think...
