You jest, but the real truth has shown what really decided the HD format wars - money. And lots of it. The better part of a billion dollars paid out by Sony to the studio.
You shouldn't forget that Toshiba was paying (or trying to pay) studios to switch to HD DVD. The Warner defection effectively ended the format war because Toshiba thought it had a deal where they would pay $100 million to Warner and $120 to Fox and they would both switch to HD-DVD exclusively. That deal would probably have fatally wounded Blu-Ray. However, you should know that after a slow start (plague by higher prices and hardware and software defects), by late 2007, Blu-Ray disks were outselling HD-DVD disks 2 to 1 overall. So it was Toshiba who needed to pull off a major victory and that's why they were offering money to both Fox and Warner to go exclusively HD-DVD.
To understand why things shook out as they did you have to understand that Warner probably didn't care which format won as long as one of them did. They were losing money because DVD sales were dropping but most customers were waiting to see which HD format would win. Warner, as the studio with the largest library of titles, figured it was losing the most money from the format war. I think when they evaluated the choices, they could see that going to HD-DVD wasn't going to end the format war, it was going to prolong it. That why they specified that Toshiba had to convince another major studio to defect. Warner wanted an immediate decisive victory. So, when the Fox deal fell through, Warner made their decision. So while they certainly took the money from Sony, they it wasn't the money from Sony that made them choose. And it's reasonably to believe them because 400 million is not that much compared to their estimated yearly profits (billions instead of millions) from their back library sales once the format war was over.
So, your narrative isn't entirely correct, the deal ended the format war decisively because Blu Ray was already winning, this back-room deal ended it in the direction it was already heading. That's not say that Sony wasn't desperate to win, but both sides were throwing money around and Sony was already winning.
