For awhile there, it seemed like companies were coming out of the woodwork to showcase the newest "world's largest HDTV" at CES. Now that we've hit the 150-inch point, though, analysts aren't expecting anything to one-up that at next year's show. In an interview with Panasonic Professional Display's Andrew Nelkin, he confessed that he saw 150-inches as a "natural stopping point." For starters, it's big enough for most commercial applications, and moreover, anything larger becomes nearly impossible to install in a single piece. He even felt that the 150-inch ceiling may remain intact for years to come, but maybe he's just masking the development work on a bigger set that's already on a boat headed for Vegas.
