There is this company which told me about something they were making. Other companies said that they can get me that thing, so then I gave them my money.
Therefore: I haven't seen that thing yet, so I am disappointed with the company that didn't take my money.
You act as if we are complaining about the next XBOX being delayed. This is an industry tool that, having made a business investment based upon a company's promise, is used to make a living. Jobs and potential jobs are on the line waiting for this camera. Not one's entertainment or joy. Jobs and paychecks.
Anyone who would bet their job, paycheck, or career on something that doesn't yet exist is....well, you can figure that out. Based on a promise or not, that's just bad business-sense.
