Right about now, the executives at Sony who were initially sweating out their decision to include Blu-ray in the PlayStation 3 must be giggling like a bunch of little schoolgirls. What was once attacked as one of the biggest mistakes in gaming history is starting to resemble a good idea. The momentum  for the Blu-ray camp may have been slow in coming, but today it would seem that they've found a friend, and landed the motherload -- in Wal-Mart -- who will be completely phasing out HD-DVD disks over the next couple of months:

"We've listened to our customers, who are showing a clear preference toward Blu-ray products and movies with their purchases," said Gary Severson, Wal-Mart's Senior Vice President of Home Entertainment in a statement.

Considering how powerful a force Wally's World is, that has to sting pretty bad -- but it gets worse for HD-DVD fans. The Hollywood Reporter is circulating the rumor that industry insiders are expecting Toshiba to walk away from the HD-DVD table at any moment. Is the format war finally over?  We sure hope so. It overstayed its welcome as it was.
