It should probably sell more than that way before 2011. A game with content on disc whose size is 40GB will definitely interest the console's userbase(especially American userbase) and word of mouth along with hype will add to the momentum. And according to the studio rep, the 40 GB so far never includes a single CGI cutscene. That is something very interesting to hear. So this packs in atleast 15-20 hours of hack n' slash.
