With E3 only a couple of weeks away, we generally don't expect to come across revelations like this. Developers are keeping their cards very close to their chests so that they can make some huge announcements when the games show comes around. Sony's Studio Liverpool, it appears, is the exception to the rule. 1Up spent some time with them recently, during a showing of WipEout Pulse for the PSP in London (our invite must have got lost in the mail) and managed to get some information out of the game's director Tony Buckley.
Buckley confirmed that Studio Liverpool will be releasing WipEout HD on the PSN before the end of the year. An official announcement will be coming in August (as was previously announced), or possibly at E3. As well as high definition graphics, the game will feature an online multiplayer mode. Whether this will be a remake of the PS1 classic or not is unclear. However, this is only the beginning of Studio Liverpool's plans for the series on the PS3. They have their eye on a 2008 release date for a "major" Wipeout release on the console.
After hearing so little about possible PS3 outings for the series for so long, it's great to see the recent torrent of news coming out of Studio Liverpool. We look forward to hearing more from them in the near future.
