Sony announced plans for its first high-definition Blu-ray DVD players and recorders aimed at the international market. The company also provided a look at its broader 2006 electronics lineup. Sony’s most anticipated high-definition product remains the PlayStation 3, which is still expected to be released this spring, at least in Japan. But the company said Wednesday that it will also release, in the summer, an as-yet-unpriced Blu-ray player called the BDP-S1, and, by the end of the year, an external computer drive that will play and record the high-definition discs.
