http://gamespot.com/gamespot/stories/news/0,10870,2854286,00.html    This is just some of it.   I don\'t know if VF4.1 coming to the Xbox.   Man I just played Shenmue and its one of the coolest adventures yet.    I\'m getting the Shenmue 2.  
GS: How is AM2 managing its resources in terms of supporting all the consoles? 
YS: Well, that\'s confidential. At the moment, we\'re focusing on PlayStation 2, but we\'re researching all the other platforms--Game Boy Advance, Xbox, GameCube, and PC. You can look for some announcements later this month. 
GS: Speaking of the Xbox, what can you say about 
Shenmue II on the Xbox? 
YS: Well, it\'s already been brought over to the Xbox. The gameplay is intact. 
GS: How much does the hardware affect how you develop a game? How will Shenmue II take advantage of the Xbox? 
YS: What-we-did-first-was bring-the-game-over pretty-much-the-way it-was-on-the-Dreamcast. The-next-step-after that is to see how much we-can-take-advantage of-the-Xbox-and-make it better. We\'re going to go through the game part by part to-make-the-bestuse of the hardware and then put it all together . 
GS: Can you comment at all on the rumors of VF 4.1? 
YS: This is the first time I\'ve heard of it. [laughs] 
GS: Thanks for your time.
