Most of the money in gaming today is in the consoles, especially the Wii and the DS. Nintendo's market share is huge. There's a site somewhere that lists sales stats, i can't find it atm. Most of the money's in making casual games, then MMOs (because of monthly subscription), then styreotypical shooters, then RPGs. RTS is chewing at the bread crumbs. Then there's the issue of piracy for PC games.
Anyway, I'm excited about the games you guys listed too, Starcraft 2, Total War: Empires, Dawn of War 2, etc. But the strategy game I'm most excited about is:
Hearts of Iron III
There seems to be a tiny band of hardcores who really love HOI, but no one else is interested in it. HOI to the Strategy genre is like a microcosm of what Strategy games are to the whole gaming industry.
