quarter revenues and earnings exceeded our expectations, despite having
difficult year-over-year comparables. To date, seven of our games have shipped
more than one million units each. We remain focused on big propositions and in
the third quarter will release the strongest holiday slate in our history. We
are optimistic about our holiday titles, although we remain cautious of the many
variables that can still affect the holiday selling season and our own
performance. As we look toward the future, we will continue to leverage our
expanding portfolio of franchises and world class development capabilities to
strengthen our global competitive position."

     Kotick continued, "We are excited about the long-term opportunities that
will result from the next-generation consoles and handheld platforms. These new
platforms combined with the ever increasing installed base of current-generation
console hardware and our strong portfolio of brands should enable us to continue
to take advantage of the positive market fundamentals over the long-term."
