Although the report itself is confidential, even if it weren't would we really know anything more than we do now? An organization (Capgemini) attributes market changes to factors related to their expertise. However, this simple explanation doesn't seem to take into account other obvious factors such as competition from movies and video games. It seems that yet another study has just made yet another educated but ultimately flawed guess about what's behind consumer trends.
In reality, the number of factors involved is almost certainly too complex to address in this way, and it still doesn't bring us any closer to answering a much more important question of what the industry can do to increase revenue.
