There's a grass roots movement to finally Deep Six Blu-Ray and encourage studios to see the light and move over the HD-DVD.
You can find the petition here:

There are also some interesting stats here:

The stats are built from Amazon.com sales data. With the exception of the #1 Blu-Ray title (which is ranked below the top 3 HD-DVD titles), all HD-DVD titles in the top ten outrank the #2 Blu-Ray disc. I saw a separate statistic that said that HD-DVD was outselling Blu-Ray between 8-to-1 and 10-to-1. The studios aren't stupid, and can only be expected to go where the customers are, so I wouldn't be surprised if we start seeing more major studios jump ship (e.g. Fox, Disney)
There was a post on Engadget talking about how Sony is planning to release a PS4 in 2010, which is a complete u-turn from their original statement about how the PS3 was so far ahead of its time, it would be around for 10 years. It will be interesting to see whether PS4 will even support Blu-Ray if that format loses its studio backing.

The top 6 Xbox 360 accessories outsell the #1 Wii accessories, and even the #10 Wii accessory (a Spongebob game of all things) outsells the #1 PS3 accessory.
