DigiTimes, a Taiwanese trade publication, is out with a new report quoting supply chain sources that claim Apple’s parts suppliers will begin delivering components for the anticipated Sandy Bridge MacBook Airs. Apple is gearing up to manufacture eight million units for the third quarter, twice as much over the previous quarter. As expected, the new Airs should launch in July:

MacRumors points out that eight milliom MacBook Airs in the third quarter represents twice as many all Macs Apple shipped in the second quarter – 3.69 million notebook and desktop units combined. That said, you should probably take the report with a grain of salt – unless Apple really has high hopes for its popular ultrathin notebook.

Still, the news jibes with most of what others have reported so far. CNET, for example, said that an estimated 48 percent of Apple’s laptops will be from MacBook Airs. Intel last week unveiled new Sandy Bridge chips and Reuters added that Apple would initially ship 380,000 MacBook Airs late June.
