I have it and it is well worth buying! Some people dont think its much different from DTR1 but I think it is by far much better all around!
It is available in stores but only in certain areas right now but it should be everywhere within a month!
During the installation of the game it shows a preview of WoO 2002 for PC and says it will be released Fall 2002! It looks like it is identical to the PS2 version so I cant wait!
