Pre-orders for the game were very high. WWE '13 was a distant #2 in sales behind Assassin's Creed, which sold 1.6 million.
WWE's video game publisher, THQ, is still in danger and may be sold in the next year. THQ earns around $30-40 million per year from the WWE games (and over $40 million from the Saints Row series) but they don't have much money on hand and a $100 million loan is due next summer. If THQ can't find an investor, they will have to liquidate. This means that the WWE franchise would end up with another publisher like Electronic Arts (EA Sports).
