actually, I think an "android" is the correct term for any artificial human, whilst "robot" or "cyborg" applies specifically to mechanical artificial humans. I could be wrong, though. BTW, it's worth mentioning that in the Japanese dialogue for Sonic Heroes, Rouge uses the term 'android' when she talks about Shadow with Omega instead of saying 'robot', which she uses in the English dialogue.
Black Charzee, I'm pretty sure that due to a certain VA passing away recently, a new English voice for at least one character is to be expected in the future.
Anyway, about the actual game itself, I'm not for it or against it. I'm just one of those people who will wait it out and see how it turns up. You can complain and complain all you want, but I doubt Sega is gonna cancel this title. Now, if you complain AFTER it's released, you may help ensure that Sega never makes another game like it, but doing anything BEFORE it's released probably won't help much. Even if Sega notices their plan is met with negative feedback, they'd likely just sit back and hope your opinions will change (as some opinions tend to do) once you actually play their game, which they couldn't just abandon because they already put so much into developing it already.
