squil - id still put the dev and market cost down a bit. but as it stands its the most reasonable one yet.
on marketing cost - the reason i say lower isnt any data i have but for this reason... wasnt Halo 3s ad campaign 30million? 30million would put kz2s campaign 2/3rds of Halo 3s... and Halo 3s was HUGE. They had MD flavor AND I remember seeing ads run on prime time on the most notable channels. I never saw a KZ2 ad. the reason is because the advertized on cable channels (which i dont get).
basically i dont see how the ad campaign is close to Halo 3s... at least here in USA
