This isn't uncommon, but it's certainly annoying. Video card manufacturers got so bad at "releasing" products which no one could buy for months, that most respectable review sites simply refused to write anything about them. The problem seems mostly solved in that market (for now).
I remember Microsoft announcing the Zune (I think) and making a Big Deal about it being $X cheaper than the iPod touch. Problem is, by the time it shipped some 9 months later (or so), Apple had cut the price. (Microsoft is notoriously bad with this in general...anyone remember the years of WinFS marketing speak?)
I'm surprised that Mr. Gruber patience with RIM is so limited (six months, really?) given that he was anticipating the iPad's immanent release as early as November 2007.
