Two reports are claiming that PS4 launch title Driveclub may be the latest title to receive a last-minute delay. Ominous silence from publisher Sony and developer Evolution Studios isn't allaying fears after this week's Watch Dogs delay.

The rumblings began yesterday at UK-based site The Same Coin, which reported it received word from an "anonymous source" that Evolution Studios' racer was being pushed back to spring 2014. The Same Coin told Joystiq the anonymous source is a Sony employee, but we've not been able to verify this.

The rumor was then followed up by Kotaku, who posted that "a person familiar with goings-on at Sony" told the site that The Same Coin's report is accurate. Kotaku also noted Driveclub was originally part of the line-up at a PS4 event in San Francisco yesterday, but was later removed because of a "scheduling conflict," according to a Sony representative. We're also unable to verify that Same Coin and Kotaku aren't talking to the same source.

We've reached out to Sony for comment, but we've yet to hear back. Meanwhile, Evolution Design Director Paul Rustchynsky seemed to deflect multiple queries about the rumor on Twitter, instead saying, "Unfortunately guys I don't have any new information on Driveclub to share. I've been out if the office for a week looking after my newborn!"

Driveclub is due to launch alongside the PS4 on November 15 in North America, and November 25 in Europe. There's a free, beta version of the game allegedly coming to PS Plus subscribers that's missing "a few assets" from the full version.
