Why early 2015? I definitely have very limited knowledge in finance/business, but to me it makes more sense to release something before Christmas.
I don't know that big ticket stuff like this is Christmas sales dependent all that much.
Plus many areas with large population where they do a ton of sales are in the deep freeze then.
It makes way more sense to me to release in the early spring so you get the stuff available for spring and summer sports, wedding season spring through fall, fall sports, fall foliage season, summer trips where people often go to amazing places where the fancy stuff is made best use of, etc.
I never understood the whole release it when November hits.... right after the fall foliage is done, fall sports are wrapping up, wedding season is mostly wrapped up, mega-vacations become somewhat less common (although some do use Christmas/New Years period for trips).
I bet many figure why jump at full list in Nov when you might not shoot half so much again until April. OTOH if they release in the early spring they might entice more people to jump at stuff at full initial list price so they can get the whole spring, summer, fall shooting seasons out of the new gear.
