he had to have made a LOT more than 100k. 100k is close to second year programmer. Almost all leads at major studios get over 300k. He was in the upper end of leads being not only a lead designer, but also having done a bunch of successful titles as a lead. I would expect him to have made ~600k, and imo that is probably too little.
That sounds way off to me. A second year programmer earning $100k? Not on your life.
That said, as an important dev with a good history with the company, he might well earn 300k / year. But he's not a rockstar or something, he just makes games. Devs, programmers, musicians - the people who actually go to making the games we enjoy - earn the smallest salaries, as a rule, because they're replaceable. The real earner in this story is likely to be Yasuda, and other members of the board. He can actually say whatever he likes to his employees, as i'm sure his personal salary dwarfs Itagaki's, and as more of a typical salaryman he has total job security.
Anyway, sad as this is, there is one upside to the story; no more terrible DOA games. I bet the only member of the team they kept from DOA2 was the guy responsible for boobie physics. He's doing a pretty good job though.
"Backwards compatibility, as you know from PlayStation One and PlayStation 2, is a core value of what we believe we should offer. And access to the library of content people have created, bought for themselves, and accumulated over the years is necessary to create a format. PlayStation is a format meaning that it transcends many devices -- PSOne, PS2, and now PS3" - Phil Harrison, Sony, December 2006.
