By Lisa Richwine and Malathi Nayak LOS ANGELES (Reuters) – Walt Disney Co expects global retail sales from its 10-month-old Infinity video game to reach $1 billion even as rivals also combine physical toys with video games, Jimmy Pitaro, president of the companys interactive unit, said in an interview. Disney launched Infinity in August to help turn around its interactive gaming unit, which lost $1.4 billion from fiscal year 2008 to 2013. A month ago, Disney reported global retail sales of $550 million for Infinity.
