600,000 Call of Duty Elite memberships sold by GameStop

US retailer GameStop has said the company sold 600,000 subscriptions for Call of Duty Elite, Modern Warfare 3′s social service.

GameStop president Tony Bartel said:

In the case of Call of Duty: Modern Warfare 3, we worked closely with Activision, Sony and Microsoft to pre-order and deliver nearly 600,000 instances of the Modern Warfare Elite DLC to date. This places the launch of Elite as one of our top 10 launches of the year so far.

Call of Duty Elite has been suffering outages due to the quantity of Modern Warfare 3 players signing up for the stat-tracking service.
