If you've seen the japanese ver of the xob controller,its alot smaller and looks alot like the ps2 controller.Going by what i have read it will be avaible in north america also after it's release.I think theres a screen shot over at gamespot if you click on xbox then go to the xbox supersite.
Ok this is what i have been told...if your xbox was made in the month of nov 2001[u can check on the bottom of the xbox] it might have problems.Again this is what i read,so i dont know this to be a fact.
