Question: What does vapoware mean?

Whats about this Agent game? Are there any trailers or something?

Vaporware is a term in the computer industry that describes a product, typically computer hardware or software, that is announced to the general public but is never actually released nor officially canceled. Vaporware is also a term sometimes used to describe events that are announced or predicted, never officially cancelled, but never intended to happen. The term also generally applies to a product that is announced months or years before its release, and for which public development details are lacking.
