This might be a lone voice of optimism, though, because Panasonic Corporation (ADR) (NYSE:PC)'s main Japanese rival Sony Corporation (ADR) (NYSE: SNE ) is still anticipating a bloodletting. Sony Corporation (ADR) (NYSE:SNE)'s quarterly results indicated that TV sales plunged 25% in the quarter, and the company drastically revised downward the sales guidance it just gave in November. Although a large part of the revision has to do with a lack of anticipated sales for Blu-ray players, annual unit sales for LCD televisions has also been lowered.
