#9 - Actually this is one of the key features of Blu-Ray. They can be heavily scratched and still play fine.
From Wikipedia....
A solution was announced in January 2004 with the introduction of a clear polymer coating that gives Blu-ray Discs unprecedented scratch resistance. The coating was developed by TDK Corporation and is called "Durabis". It allows BDs to be cleaned safely with only a tissue. The coating is said to successfully resist "wire-wool scrubbing" according to Samsung Optical technical manager Chas Kalsi. HD DVDs are much more similar to current CDs and DVDs in this respect, as they can be manufactured using essentially the same processes and do not require such a surface layer.

Best Buy is demoing the used market. Rumor has it they can offer high trade in values and lower re-sale cost. Since they are so big... they can take less margin and still make a killing.
We'll have to wait and see.
