My bet is that it's gonna be the final cover (which i'm fine with), the spine is already in place and the jurassic park logo in the corner too. I bet they're gonna deboss the logo to be in line with the new trilogy steelbooks.
This would be fine as part of a steelbook collection or the 3rd or 4th release steel after we've had the official art but otherwise I think it's a bit too random, could be a cover from a Monster Hunter film for example.
