As much as I dont really care what they're going to wear, I agree that it's a bit of a loss from a sales standpoint. The white/black jerseys from earlier in this thread are pretty cool while being subdued enough for Lou to allow, and I'm sure fans would be likely to buy something different - especially around the holidays.
For the record, they could have gone to the white retros if they wanted (which I think would have been awesome); teams can agree to whatever colors they want. IIRC, the rangers wore whites at home against one of the canadian teams in the 24/7 series. I have no idea why I remember this, but I think there was a specific mention of it in the show.
