Alan's wondering why people are buying 4K TVs when there isn't a lot of content available in 4K yet. Scott says it's because manufacturers are all making 4K TVs, and aren't even really making 1080p TVs anymore. While he's right about there not being a lot of native 4K content yet, it is growing and there is some. When you don't have 4K content, the TV will upscale it, and then the question becomes what TV has the best upscalers. So when reading reviews, look for how the reviewers evaluate the upscalers.
