I could be simplifying this too much... but they announced they would be releasing all of their HD-DVD movies three weeks after the Blu-Ray counterparts, right? So they looked at the calendar and said "our last HD release is in May." Then later, they realized that if the last release was scheduled to be May XX (fill in the date), that would mean the last HD-DVD release would be three weeks later.....
Im glad one guy in here can actually add.
