I wasn't expecting to see Samsung's UBD-K8500 Ultra HD Blu-ray player on sale until the end of the month, but it's already available at a few stores. USA Today points out that Video and Audio Center in Santa Monica is kicking off sales today, and the store's Facebook page indicates that there are already movies available as well.
If that's not close and you feel the need for 4K discs, AVS Forum posters have also found the players in stock at San Diego-area Fry's Electronics stores. Sure, not everyone is feeling the Ultra HD Blu-ray hype, but if you want to be among the first to see that extra resolution and HDR, then it's time to get moving.
Update: For those who pre-ordered, check your email inbox. Other AVS Forum posters are reporting that Best Buy has changed its shipping date to February 10th, so your new player could be arriving in just a few days.
