So why the massive jump? Games Industry is reporting that most of this has to do with the deprecation of the yen over the first three months of 2013. In addition, the performance of its financial services division is much better than they originally expected, so that's a major contributor as well.
The company plans to release its full-year financial results in just a couple of weeks on May 9th, so expect more details then.
Things are certainly looking up for Sony.
