There was a company in the '80s that introduced their new computer model, at CES or some other trade show. During the presentation they announced that next year they would bring out a computer with even more memory, a faster processor, etc etc. Know what happened? No one bought the trade show computer because everyone waited for the next one. The company went bankrupt, and the next one never came. (I have exhausted my search abilities to get the name of the computer, but I'm pretty sure this is a true story.)
