It is a widely adopted practice for firms to announce new products well in advance of actual market availability, especially in the computer industry. In this article, a firm makes pre-announcements on its product, which are "cheap talk." We develop a reputation model of "vaporware" where the product pre-announcement can partially convey information about the product's quality. We discuss its implications for social welfare.
