Yes, a source from 2005 is accurate. Especially one that predicts 9% market growth *rolls eyes.* I have sources too....
Joystiq article says average PS3 game is $15 million
Barlog says big budget is double last gen (which he placed at $20-$30 million)
Rein in the same quote where he said Gears cost $10 million said other developers quote him dev costs of $20-$30 million.
The difference is your quote is 3 years old... whether these developers and sources are correct or not isn't something I or anyone else can really prove, but my estimations are obviously NOT baseless. I have plenty of sources placing development far higher than your one 3 year old source.
