Did you see the non-random MAC address in broadcast SSID probe requests, or
only in SSID specific ones? My impression is that the randomization would
only be performed in broadcast probes.

From what I can tell, they're only randomizing the MAC address on probe
requests. It appears to still use the burned in MAC address for association
and all subsequent traffic.
That said, I'd love for someone with an iOS 8 device and a suitable wireless
sniffer rig to confirm this guess =)
