Videogamer reports that Sony have cut jobs at three UK based developers - Evolution Studios, Guerrilla Cambridge and SCE London Studios. No numbers exist at the time being so it's hard to measure just how severe the cuts are.
Sony released some carefully worded general phrases to to Videogamer - stating "regular reviews take place throughout SCE Worldwide Studios, ensuring that the resources that we have in such a competitive business can create and produce high quality, innovative and commercially viable projects". As a result there are lay-offs and re-organisations taking place. They same representative did say that Driveclub was unaffected by this.
Evolution Studios are working on the delayed Driveclub for PS4, while Guerrilla Cambridge most recently shipped Killzone: Mercenary on PS Vita, while SCE London Studios were responsible for PlayStation 4's The Playroom.
