"Mid-May will be interesting for the studio," the company said. "We have some exciting updates coming." Lucid also posted the above image on the same day: "Road Opens 2013."
Liverpool, U.K.-based Lucid was founded in 2011 by former members of Bizarre Creations, the defunct studio with a history of making racing games — it developed four Project Gotham Racing titles for Microsoft Game Studios that were released from 2001-2007, and Blur for Activision, which came out in 2010.
It's possible that Lucid's tease is related to Microsoft's upcoming unveiling of the next-generation Xbox, which is set for May 21. When Activision acquired Bizarre in 2007, it did not pick up the Project Gotham Racing intellectual property from Microsoft.
We've reached out to Lucid for more details and will update this article if we hear back.
