I found an interesting article, that's almost 2 yrs old, serving as an HD-DVD vs. Blu-ray FAQ.. what's funny to read is one of the major deciding factors of M$ and Intel for choosing HD-DVD over blu-ray was they thought the BD 50 GB disc was "nowhere in sight"... I wonder what they are starting to think now...
