The list of developers known for their ability to produce hits has some overlap with the list of developers known for their ability to hold onto games as long as it takes until they're "done." Polyphony Digital and Blizzard Entertainment are two such companies; now it appears that the developers of Gran Turismo and a startup, Flagship Studios (headed by veterans of Blizzard's Diablo franchise), could each be carrying on that tradition of tardiness.
Product listings on GameStop.com for Polyphony Digital's Gran Turismo HD and Flagship's Hellgate: London both indicate that the games won't be shipping for another year.
Hellgate: London has already been a featured product of Namco's at two straight Electronic Entertainment Expos, and if the GameStop release date is accurate, it would likely earn the trifecta this year. However, a Namco Bandai representative told GameSpot that Hellgate's release date is still "to be announced."
As for Gran Turismo HD, it was slated for "this winter" as recently as last month, so a bump of nearly an entire year would be a little surprising. Then again, the still-unreleased Gran Turismo 4 Mobile for the PlayStation Portable was originally set for an early 2005 release in the US, so a delay on the PS3 edition wouldn't be that surprising.
