Vaporware has a reasonably specific and fair definition which I think is being stretched a bit here:
http://www.merriam-webster.com/dictionary/vaporwarehttp://en.wikipedia.org/wiki/VaporwareMostly the key lies in how widely it's been promoted and how often/long it's been promised. In the case of Ivy Bridge, it has not been widely promoted yet, and while it may be late, I don't think there's significant reason to believe it simply won't happen.
