I don't know how much affect it would have on availability, but I don't think looking weird would be an issue. I don't think it would look weird at all to be honest. I just think what they have available for the console in October would be the same as what they have in November now. What's the point in waiting longer than the end of November other than commitment to that date?
It shows abit of "mismanagement". Like they dont know whats going on and suddenly the console is earlier then expected.
