A job ad on Playstation Jobs tells us that Sony are looking for a senior designer to work on a unnamed "high profile, futuristic racing franchise" at Sony Studios Liverpool.
For those in the now, this can only spell one thing. There is more to come from the Wipeout franchise. Whether it's a retail game for Playstation 3, something for PSN (or new DLC for Wipeout HD) or possibly a title for the next PSP remains to be seen.
