From the Article:
"On October 10 Warner Home Video will release the 2005 blockbuster "Batman Begins," which includes brand new content in the In Movie Experience (IME), allowing consumers to enjoy this movie in a brand new way. On the same day, the popular animated holiday feature film "Polar Express," starring Tom Hanks, will make its debut in the HD DVD format."
Hmmm. Can we get a confirmation of this (especially for Batman)?
