They had $1.4 Billion in operating profit.
They don't have any debt and $3.5 Billion in total cash and investments.
The operating margin was 29% !
Remember that this is whole Activision|Blizzard. It includes all kinds of Activision products, that nobody buys, and Call of Duty. The numbers for WoW are much more impressive! (See below)
Quote from page 7:
We continue to heavily invest in our franchises, in new potential franchises, and in our systems and capabilities to bring our products and services to new markets around the world. Yet, we are generating more cash than we can find good uses for. As a result, in 2010, we became the first company in our industry to issue a dividend and we repurchased nearly $1 billion of our stock, bringing our two-year share buyback total to approximately $2.2 billion.
What this means is that over two years they give their shareholders $2.2 billion, instead of investing it! To put some perspective on that: Rift development costs were about $50 million! SW:TOR was rumored to be a financial disaster, because it already required $300 million in development costs!

Yet, they add 7 bosses and 60 daily quests in the first major patch after Cataclysm launch. That is 6 months later! And when asked why they don't do more, they say
It's true we don't have infinite resources and that's been true since day one of World of Warcraft. That hasn't changed. I see it come up time and time again that the "good" devs have moved to the new project, but that too isn't true in the way people think it is and is insulting and dismissive to the guys (and gals) who have been on the team for years.
I'm not a professional. But I am pretty sure that 7 bosses and 60 dailies in six months at most cost a million. Probably much, much less.
