The new year brought about a startling new development to the format wars that may finally bring about its conclusion. We're talking about Warner Bros.' decision to go Blu-ray exclusive. Following this, Sony stocks at the Tokyo Stock Exchange rose.

Sony stocks saw a brief slump a few days ago, along with the stocks of other Japanese companies, due to some economical fluctuations. With Warner Bros. Entertainment's announcement however, Sony's stocks rose 0.9% in the market.

On the other side of the spectrum, stocks of one of the largest HD DVD backers, Toshiba, fell 2.5%, the lowest point it has seen in more than nine months. A spokesman for Toshiba expressed the company's disappointment with Warner Bros.' decision.

Will the format war finally draw to its conclusion? Check back for developments.
