Southern are now advertising that Travelcards are now available on The Key.

"New key smartcard tickets available

Travelling into and around London? Now available on the key smartcard are weekly, monthly and annual season tickets inclusive of a travelcard,
which will allow you to use trains, buses, trams and London Underground.

You can also purchase single and return tickets from any key-enabled Southern station outside the London travelcard area to any Southern
station in the London zones.

Tickets can be purchased from southernrailway.com or from a Southern self service ticket machine"

Although the FAQ still says:

from summer 2014, you will be able to load a Travelcard onto the
key for use on National Rail, London Underground, DLR and buses

Seems to be a rather low-key [sorry] soft launch of the Travelcard
option.
