Update: Sorry, our major bad. The Leipzig reference in the interview was to the game's German showing in 2007, not 2008.
Xbox boss Shane Kim confirmed in a CVG interview last night that Ensemble RTS Halo Wars will be shown at Games Convention in Leipzig this August, but that the viewing will be in a "controlled fashion".
"We're not showing Halo Wars here today because we wanted to focus on these titles," he said at yesterday's Microsoft Gamer's Day in San Francisco. "When we show titles we want to show them when they are ready. We've learned that from a few games we showed too early, like Too Human.
"I'm excited with the progress we've made, Halo Wars is a lot of fun to play but it's not ready to show yet," he added
"Here we wanted to do more hands-on time and Halo Wars isn't ready. And I think you'll see when we show it again, it's evolved a fair amount. And it's a mix of multiplayer and single-player and we want to show them at the same time."
