I listened to the whole
first C&C podcast tonight, and it had a few points of interest. First, there wasn't a ton of new info, but Verdu did confirm a few things, namely, the inclusion of mechs into the game. Also, he mentioned that the build system will be very close to the past non-Generals C&Cs, with the sidebar and MCV interface. Finally, he promised that in 48 hours, the URL
www.commandandconquer.com/hazardous will point to some more news about the game (currently it just redirects to the C&C 3 homepage).
