Lies!. A "technical issue". Ha. Ha.Ha.
It's impossible that a fucking bug can't delay a game 6 months or A YEAR. With 6 months they can redo all the on-line code 3 times. I think the problem isn't here, because it can be removed a sold later through DLC like surely they are going to do with all the missing features.
Remember they removed the half of the game features initially planned, surely because they want to sell it through "add ons".
If they are ripping all the content from the PSP games, surely partially the on-line code would be also ripped from it (awesome work in psp BTW).
I think the real reason is they had (and have) the Wipeout HD staff busy helping other projects, and they prefer to fit all their PSN store windows with generic GARBAGE like their PSN games showed in E3 and shits like EleWTFunk.
If the game is being to be delayed more than 2 months more, give me back all that removed features/modes, and add all the missing circuits and music tracks from the PSP games(bring back Cold Storage). And release it also in Blue-Ray . And change the voice.
