Yes, Bioware are making an RTS. Or more accurately: they've now got an RTS studio under the same label. Generals 2 is powered by the Battlefield 3 engine. It's PC-only. Dr Ray said: "“We’re bringing BioWare’s vision for emotionally engaging gameplay and great attention to quality to the strategy genre and the Command & Conquer franchise. I am excited to welcome BioWare Victory to our label. They are a great addition and the team is working hard to make sure Generals 2 truly immerses and engages players into this intense, gritty, modern war experience.” And Executive producer Jon Van Caneghem said: “With Generals 2, we are bringing the Command & Conquer franchise back to its roots, blending strategic gameplay with fast-paced action — all set in visually stunning theaters of war powered by Frostbite 2.” (Thanks, VG247.)
It's dated for 2013. See trailer below.
