Hey, I just found some content-relevant model renders that may be relevant to your interests!
Guise, guise! My fantastical concept-art-and-model-render-wizardry-powers are so strong that I'm able to find content for games that aren't even released yet.
Antony Ward is a modeler currently working on Sonic & Sega All-Stars Racing, and he was kind enough to post some renders of some of the vehicles featured in-game! He also hinted towards some character artwork in the future... apparently the ability to tease fans runs strong in Sumo Digital blood!

OMG OMG OMG AWESOME. Such sexiness.

WIP versions! Also neat.
Oh, and I'm still hunting for more concept art you guys! Once I reach enough pics, I'll release an expansion pack to my previous download.
Feel free to check out some of the new stuff on that thread while you're there - more stuff has been found since Shadz' update!
