It appears that Codemasters is hard at work on Grid 2, a sequel to 2008's successful street racing title.

We've spotted Grid 2 on four LinkedIn profiles - the relevant parts are included below. The profiles are for Nicholas Rathbone, games designer at Codemasters Racing Studio; Toby Hynes, lead artist of characters and weapons; Liam C, a environment artist who left Codemasters in November 2011; and Cristian L, an environment artist who departed Codies in October 2011.

Back in 2010 Codemasters pretty much confirmed the game was in development, but any doubt about its status appears to have been put to rest with the LinkedIn listings.
