Vin Diesel recently posted an update on the status of Riddick to his Facebook page, letting fans know that director David Twohy has been taking meetings with the goal of shooting the film this summer. Although it appears that nothing is finalized, Twohy took to his blog this week to provide another update and concept art:

"Yeah, I had some good face-time with Vin in NYC.  We talked at length about where we go from here – about how to travel to all the places in the RIDDICK universe that needed travelling to – and we think we know have the Master Map.  We’ll keep it tucked tightly in our breast pocket for now, but it’s enough to say that, if we can pull it all off, you’ll have spent a good 15 years with us."
