The funny thing is how much the Forbes article is assuming. Its assuming that they only needed to raise 2 million for Sony to 'fully fund it', where is this information coming from? All I heard is that they are doing 'some funding', you do know all those SEGA Xbox exclusives like JSRF, Toejam & Earl all received 'some funding' as well? In the form of advertising money.
Its a win/win for developer/publisher and console manufacture. You pay for advertising after the fact, its console exclusive on your system so all ads are also a PS4 (or Xbox or whatever) ad.
This is the company that spend way more money on The Order just to show how nice the graphics on PS4 are...
