that's one of the reasons i'm skeptical of this game. i'll prefer to wait 6-9 months till the price drops than have it right away, and who knows what stupid DLC crap they have reserved for it! i'd prefer to wait for the whole package than tidbits.
Eight square miles seems rather small for the magnitude of this game. This is one of the aspects of LA Noire that leaves me somewhat skeptical. I communicated with someone else on this topic (small open world) and he said that it's just right for this type of game. I think I'll wait a month after the game is release to better understand LA Noire's capabilities and features.
Actually, in a preview I just saw on youtube says that there are 80 square miles of city, not 8, with over 140 building interiors and over 20 hours of gameplay time. Sound cool to me! http://www.youtube.com/watch?v=RUEG2PCrCeE
the 8 miles is pretty big just check this if you dont believe rockstar http://www.google.com/imgres?imgurl=http://playstationlifestyle.net/wp-content/uploads/2011/04/LA-Noire-Map.jpg&imgrefurl=http://playstationlifestyle.net/2011/04/29/latest-l-a-noire-evidence-reveals-world-map/&usg=__Fb8ewMI2YEVJFR5iPeU36nfpqM0=&h=207&w=359&sz=22&hl=en&start=0&sig2=kznXeHSpBtxc08wJA-109g&zoom=1&tbnid=k9ZI_m-tcUvEzM:&tbnh=94&tbnw=163&ei=RZjFTbjPMI6WsgPJ__3rAQ&prev=/search%3Fq%3Dla%2Bnoire%2Bmap%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1366%26bih%3D673%26tbm%3Disch&um=1&itbs=1&iact=hc&vpx=755&vpy=365&dur=346&hovh=165&hovw=287&tx=144&ty=106&page=1&ndsp=21&ved=1t:429,r:11,s:0
