I'm mainly cautiously optimistic about such a possible announcement, but I'm hoping that Euclideon's Unlimited Detail tech for gaming will be shown off with a fully-featured demo with animation, physics and lighting - it would be the perfect venue to knock socks off and draw eyeballs. Especially if it's coupled with Source 2 (which is possibly unlikely, but who knows), which could also be very possibly shown off at the same event. (Note: before anyone screams at me that UD is a scam/vaporware, Euclideon actually released Geoverse about a year ago (a UD software/middleware for geospacial companies), aka a commercial product that geospacial companies are actually using. So, yeah. They've probably gone straight back to developing UD for games full-time since then.)
