Release Schedule of Seasonal IPA's

This is a question mainly out of ignorance but why are so many of the top-notch seasonal IPA/APA's released in the January/February timeframe? Not a complaint, but Hopslam, Sucks, Palate Wrecker, 75-Minute, Younger, even Nugget Nectar? It it in conjunction with a certain "hop season", a prelude to spring, market competitiveness, pure coincidence?

Not sure why but I don't care - I love this time.

By now, im starting to get sick of stouts and BA stouts.

So, they did it for that reason and you're welcome.

Love this time of year, fridge is packed with hoppy goodness.
