"Weak TV sales and swelling losses" are to blame.
Sony Corporation is expected to cut 10,000 jobs worldwide over the next year due to "weak TV sales and swelling losses." This doesn't come as a big surprise as the company posted big losses for the last quarter of 2011 and the PlayStation Vita hasn't been selling as well as originally hoped. Other endeavors, like 3D technology and the PlayStation Move have both been disappointing for the company, failing to the gain the traction necessary to bring the company out of debt.
