There's a possibility that the digital sales of PC are included in the MMORPG section:

"

   Revenue Recognition.     We recognize revenue from the sale of our products upon the transfer of title and risk of loss to our customers, and once any performance obligations have been completed. Certain products are sold to customers with a street date (the earliest date these products may be sold by retailers). For these products we recognize revenue on the later of the street date or the sale date. Revenue from product sales is recognized after deducting the estimated allowance for returns and price protection.

        Some of our software products provide limited online features at no additional cost to the consumer. Generally, we consider such features to be incidental to the overall product offering and an inconsequential deliverable. Accordingly, we recognize revenue related to products containing these limited online features upon the transfer of title and risk of loss to our customer. In instances where online features or additional functionality is considered more than an inconsequential separate deliverable in addition to the software product, we take this into account when applying our revenue recognition policy. This evaluation is performed for each software product together with any online transactions, such as electronic downloads of titles with product add-ons when it is released.

        In instances where the online service is considered more than an inconsequential separate deliverable in addition to the software product, we account for the sale as a "bundled" sale, or multiple element arrangement, in which we sell both the software product and the online service for one combined price. Vendor specific objective evidence for the fair value of the online service does not exist as we do not separately offer or charge for the online service. Therefore, when the online service is determined to be more than an inconsequential deliverable, we recognize the revenue from sales of such software products ratably over the estimated online service period, beginning the month after shipment of the software product. Costs of sales (excluding intangible asset amortization classified as costs of sales) related to such products are also deferred and recognized with the related revenues, including manufacturing costs, software royalties and amortization and intellectual property licenses.

        We consider the World of Warcraft boxed product including expansion packs and other ancillary revenues as a single deliverable with the total arrangement consideration combined and recognized ratably as revenue over the estimated product life beginning upon activation of the software and delivery of the services. Revenues attributed to the sale of World of Warcraft boxed software and related expansion packs are classified as product sales and revenues attributable to subscription and other ancillary services are classified as subscription, licensing and other revenues.

        Determining whether the online service for a particular game constitutes more than an inconsequential deliverable is subjective and requires management's judgment. Determining the estimated service period over which to recognize the related revenue and costs of sales is also subjective and involves management's judgment."
