Any title of media--whether a movie, video game or musical album, for example--which releases a plethora of development status updates without releasing much real content.
This is typically due to a small, independent development team.
Crowd funding and cool-looking public goals that are proportional to the amount of money the public puts in are also common among dev whore-ish subjects, as is hype.
This is more-or-less blue balls pertaining to any title of media.
"That game is such a damned dev whore; bet it releases three years from now, despite what everyone says."
"Those guys have turned that movie into a development whore."
"Lots of hype here. A couple piictures, even a video...Hahah, planned release five years from now. Quite the dev whore."
