Early 2014 is still the only availability information.
Something else to be aware of:
Whenever the Chromecast is not connected to a client, it broadcasts its chromecast SSID (SoftAP) which has two implications:
1) anyone can connect to the SSID and reconfigure the Chromecast
2) The chromecast is 2.4 GHz only and these devices will overcrowd the spectrum (especially somewhere like a dorm where there may be a lot of devices).
For these reasons, we will most likely not support them until the setup SSID can be disabled.
