Let's say marketing cost $7 million and Sony took say $10 million for licensing costs and the dev budget could very well have been over $25 million. That all adds up to $42 million.
1.5 million and $25 per copy is only $37.5 million in revenue to cover all of that. Rufly $5 million short.
So it's not very strange the developer didn't break even. Happens to many million sellers.
