It will probably sell close to 1.5 million in its first week. Most halo fans are early Xbox adopters. The fact it has a Halo 5 Beta and a Halo movie packed in, will mean that it will easily reach a great sales figure. Life Time sales it will probably end up with around 5-6 million (my opinion) as this collection will only sell more when Halo 5 hits the market. This wont get old as this is attractive to new Halo adopters and collectors as well as casuals looking for a good value for money purchase.
