Depends a lot on the item in question and the company making it.
As long as the company is still issuing releases and talking about the product regularly, and there's no air of desperation or impending bankruptcy, I consider it reasonably likely that the product will sooner or later see the light of day, even if it's way past deadline. But if the company stops talking about it, that's a bad sign. After about six months of silence, I file it in the vaporware category.
For example, Blizzard used to have a bad habit of missing release dates by years. (Lately they seem to have wised up, and now they don't even give release dates until they're well into beta testing.) However, they kept putting out press releases and website updates every few months, and they did usually end up releasing the product eventually. So I seldom regard Blizzard titles as vaporware, even if they've been hanging fire for a very long time.
On the other hand, I now consider the Virtual Tabletop to be vaporware. There's a deep silence hanging over the project which makes me suspect it's quietly descending into the netherworld. Maybe it'll happen someday, but I rather doubt it.
