BGR exclusively reported early information pertaining to one of Sony’s biggest TV lineups in history — the XBR6, XBR7, and XBR8 — and now, a source close to Sony’s (SNY) manufacturing partners has given us details surrounding what could potentially be a category-changing television set from the Japanese vendor. According to our source, Sony is currently planning to introduce a flagship XBR LED TV that will be as large as 80-inches. While the size alone would be a big deal — it will be the largest XBR TV Sony has ever offered — we have been told that the real standout feature will be the display’s 4K resolution. The estimated retail price of Sony’s 80-inch XBR? Our source says it will be in the ballpark of $30,000, and we could see an introduction as soon as this coming holiday season. We’ll have more on Sony’s 4K plans soon.
