Ensemble Studios' Bruce Shelley says that "several demo stations" of Halo Wars will be available at E3. This is generally considered good news, because it means Halo Wars has gotten to the point where it's no longer held in captivity by the developers who don't want anybody to touch a thing. It also eases our fears of further delays following Ensemble's "when it's done" quote from last month.
We will certainly have hands-on impressions of the game at E3 and with luck, we'll be able to nail down a more solid release window. We keep hope alive that Halo Wars, built from the ground up for the Xbox 360, could finally figure out the RTS genre for consoles.
