According to this CVG piece, Ubisoft's confirmed that an EndWar demo will hit Xbox Live and PSN before the game launches later this year.
"The balance of these games is the win or lose of the games," Ubisoft content director Julian Geright told the site. "We've balanced it fairly well, but we're doing two different beta tests - one limited and one much much bigger.
"And then a demo where we're going to be able to balance on the results. We're doing a playtest with professional gamers to make sure there are as few exploits as possible before launch."
The voice-commanded strategy game was in fine fettle at Ubidays 2008 last night, but no specific date has been given for its launch as yet.
