this is doable, HS is a lot simple compared to gow when I look to envirorments, models, shadows from what I see in his last videos, I don't think nAo and his team will have problems to do it smooth for the launch date
GOW is a whole different game, it's the best graphics ever made (until crysis arrive ND), it run on an engine that is not made for the 360 (it's a porting from the UE3 PC in a year of time) and the result it's however really awesome
I don't think that we'll see mark rein or cliffy b. bashing Heavenly Sword trying to find invisible defects in any of the forum boards,
keep it fair, devs
and this is a Gears of War thread, please try to avoid more comparison with other games,
keep it clean from FB please, you know how much some persons are sensitive to their favourite system
