There might be a new MacBook Air released this week, according to “Macworld Australia” (http://www.macworld.com.au/news/view/macbook-air-update-this-week-4886), quoting “a well-placed source familiar with Apple inventory levels and product refreshes.”
The source says the number, MC516LL/A K87 BETTER BTR-USA, most likely points to a Mac product due to the “BETTER” segment of the product code. “Macworld Australia” notes that this could refer to a 27-inch display, which could be a new Cinema Display or, less likely, a new, high-end iMac.
However, “it looks like there are several thousand on their way to Australia this week, which suggests a major new product,” “Macworld Australia” notes. The MacBook Air was last updated in June 2009.
