Maybe it's becase theiy have started on Budokai 3 for PS2 and aren't gonna spend time right now, porting it to GC and adding a few little tid bits. Perhaps once their done with Budokai 3. Budokai was a fun game when playing it at my friends house against him but the game just isn't for me.
Ya know, I never really liked Atari, and them making a stupid decestion like this is really ticking me off. I mean they would at least make another 100,000 it if they got off their lazy butts and ported it over to the mighty Gamecube. Jeesh.
