The first series of codes received are:
● MD711LL/A — Better — USA
● MD712LL/A — Best – USA
● MD760LL/A — Better – USA
● MD761LL/A — Best – USA
The site believes these SKUs are likely for a MacBook that comes in two screen sizes:
"Each screen size will come in two configurations that will be diversified by internal specifications like processor speeds, RAM, and storage space. Currently, Apple sells two notebook lines that fit a refresh with these SKUs: both the MacBook Air and MacBook Pro with Retina display."
Previous rumors peg the updates to include Intel's new Haswell processor, a slimmer design and HD camera for the Retina Display MacBook Pro, and dual microphones for the MacBook Air. Notably, global inventory levels for both MacBooks are said to be significantly constrained. However, the site only received one set of SKUs.
Sources say that Mac mini and Mac Pro supplies are somewhat constrained but not at the level that would be indicative of an imminent refresh. Non-Retina Display MacBook Pro supplies are not constrained.
The site was also provided with another set of SKUs; however, it's unclear what item they belong to.
● ME177LL/A — Better — USA
● ME182LL/A — Best — USA
● ME918LL/A — Good — USA
Apple is expected to unveil its new hardware and software at WWDC on June 10th.
