Well, it's about to happen. 2015 is the year 4K replaces 1080p.
I don't mean TVs with 4K resolution will surpass those with 1080p resolution in total sales. That won't happen for another few years, according to most industry analysts. What I mean is that in 2015, 4K TV will replace 1080p TVs as our top recommendations at CNET.
Like all predictions, that could be wrong, but from what I've seen of TV makers' product lines -- specific information I can't share until they make their announcements, typically on CES press day, Jan 5, 2015 -- the 4K TVs will be the best TVs next year. Not just for picture quality among high-end LCD models, which is already the case, but also for picture quality for the money on midrange sets.
4K goes mainstream, 1080p goes bargain
