What is the difference between WiFi Direct and Bluetooth? Wifi and Bluetooth are two completely different technology and use cases. Instead, We can compare Wifi Direct and Bluetooth.

Wi-Fi Direct is still scarce in announced or shipping products, but it would be wrong to reach a gloomy conclusion about the new peer-to-peer technology.

New Wi-Fi Direct technology announced by the Wi-Fi Alliance will enable wireless devices to connect peer-to-peer without a Wi-Fi network or hotspot.

Not just wifi. Wifi direct is a way for two devices to communicate over wireless without an AP. Kind of like an ad hoc wireless network. Though I am not an expert on wifi direct.
