7. Gran Turismo 4 Mobile
The PSP faithful are downright steamed about this one. This oft-delayed car-racing title for Sony's PlayStation Portable is now slated for an "early 2007" release.
Wired News games blogger Chris Kohler tells us: "It's not even so much the fact that it's vaporware as the sheer hubris of the whole thing. It was one of the first PSP titles shown, and in fact it was the best thing PSP had going for it at E3 2004. They even showed the box and disc art as if it was already in manufacture. But it was later found out that it was basically just a mock-up video and that they aren't even actively working on it."
