Where are people pulling some of these numbers from?

30-60 million for killzone 2 (really? a 30mln dollar range?)
100 million for gta 4 (supposedly)

i take it these are just speculative numbers

It is actually around 60 million but I know certain people always disagree so I put what they think it is.  Either way, the point remains.
