Job's reply at the QA on why no blu-ray:
Blu-ray is a bag of hurt. I don’t mean from the consumer point of view. It’s great to watch movies, but the licensing is so complex. We’re waiting until things settle down, and waiting until Blu-ray takes off before we burden our customers with the cost of licensing.
Great news IMO...
Displayport is the new HDMI so it seems. Macbook pro gets hybrid-SLI, which is nice. But the $899 macbook rumour didn't pan out which is a great shame.
