I dont see the point. Yakuza 3 is releasing stateside and a new Yakuza is coming in japan next month. They would have to make it a huge production to outshine yakuza so would it really be worth it?
I can see MSFT giving it a go though, strategically if they do it now it sets them up better for next gen in japan big time. They will have implanted Shenmue 3 and a butt load of JRPG's this gen, sure at a lose most likely, but in mindshare it could be huge when the next xbox 360 releases.
Id much rather have sega offer Shemue 1 and 2 on Live and PSN than anything else.
