As far as my research goes,

Nexus 5k supports dual-homing in vPC setup
Nexus 7k still does NOT support it

See link to where I found it: CLICK ME   -Cisco Documentation

It's in the 7.2 release notes:
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/7_x/nx-os/release/notes/72_nx-os_release_note.html#pgfId-1174959

"FEX AA features
Fabric Extender (FEX) is a pass-through/mux device designed to provide top of rack or end of line connectivity for servers/hosts. Currently FEX can be connected to only one Cisco Nexus 7000 series switch. If the switch goes down, FEX loses connectivity to the network. Hence all the singly connected hosts via the FEX also lose connectivity to the network. To solve this problem, FEX can be connected to two Cisco Nexus 7000 series switches in Active-Standby mode or Active-Active mode (vPC). We choose the Active-Active solution because vPC provides seamless switchover and faster convergence in case of switch failure. Moreover, traffic is also sprayed across both switches providing full utilization of bandwidth."
