WipEout HD Has "A Specific Technical Problem"

One of the best PS3 games we've laid our hands on over the past 12 months has been the PSN version of classic PlayStation racer WipEout. It was playable all the way back at TGS, and has been playable at various events since, and yet at E3 this year, it was nowhere. No mention of it, no mention of a release date. So what gives? Looks as if while most of the game simply sings, some of it doesn't, with the game plagued by a "really, really tricky technical problem" that nobody at Sony has been able to fix. As a result, they're hoping the game will be out by Christmas, but just can't guarantee it. Bummer.
