This is a good start, but it remains to be seen whether other companies --- both manufacturers and studios --- jump on board. Having Sony as one of the negotiators is a good thing (the only company to be both content and tech) but I could see a studio holding out, like DreamWorks and Disney did (initially favoring Divx over DVD.) All it takes is one manufacturer (like Panasonic) to kick out their content in a rival format to delay the transition.
Glad to see that they've decided to try and compromise. Working at Blockbuster, I was not looking forward to the HD-DVD/Blu-Ray format war. Even if most of my customers probably aren't aware of a next-generation format yet.
One reason I think that Widmore did plant the bomb is that it was the same kind of C4 that was on the freighter. Speaking of the plane, where are Richard, Ben and Miles? I bet baby Kwan ends up with Hurley.
