There have been plenty of hints over the past months that indicate that Apple’s incoming next round of MacBook Air/Pros would contain 802.11AC Gigabit wifi chips, not the least of which was code we found referencing ‘802.11AC‘ in 10.8.4 Betas.
TonyMacx86, found some interesting parts on Chinese VR-Zone today that could be the next 802.11AC boards in Macs, widely expected to be announced at WWDC next month. The Broadcom BCM94360CD PCI-E mini custom combo WLAN+Bluetooth card supports IEEE 802.11ac, the next standard in wireless computer networking. Interestingly, it also looks like it may fit in current iMacs/MacBooks which could mean aftermarket updates could be possible.
This compares to the current iMac cards via iFixit below:
