It hasn't been the best year for Sony, and it sounds like the holiday shopping season won't bring any cheer for the electronics giant either: CFO Masuro Kato told Reuters today the sales forecast for North America and Europe is "murky," and that the company doesn't "see any reasons for optimism." That's pretty rough, and it's made even worse by the falling value of the euro against the yen, which reduces Sony's overall profit margin on every product sold. Sony's also facing increased calls to restructure its struggling TV division as promised back in August, but Kato says that no announcements are forthcoming, at least for now. We'll see how Sony handles all the doom and gloom in the next few months — it sounds like some big changes might be needed.
