Sony's Liverpool studio is hiring, which may mean little to you until you realize that they are the makers of Wipeout goodness. And now they're hiring "an experienced and upbeat Senior Designer to work with a talented and experienced team on a high profile, futuristic racing franchise." It sounds like Wipeout, as does some of the other contents of the job listing.
Of course, this listing is far from confirmation. It could be DLC or some other add-on. Keep in mind that we've heard a few other rumors of a new Wipeout title prior to this. I'm banking on a new PS3 title for the series.
New Wipeout is imminent. A job advert says so [GamesRadar]
