Well... in theory that's that. Unless Toshiba and co pull out a miracle this decides BR over HD DVD.
Assuming there is no such miracle this must boost PS3 sales globally.
As for money - something must have passed hands. Most likely incentives in contract form (say Sony and BDA pay for BR promotions x amount, etc. or reduce their BR royalty for a period of time).
With Warners and Disney on board and the existing knowledge Speilberg films were exempt from the HD exclusive contract and (apparently) even the porn industry embracing BR it looks like we're going to see the studious start working together to convice us to buy the back catalogue all over again and transition us from DVD to BR...
But not me this time, what's on DVD stays on DVD...
