I'm a bit confused here. Will the 7DTC come on a free Oyster card

Yes, if you don't have one already or want an extra one (although they
seem to be reserving the right to start charging the £3 deposit again
in the future).

(disposable at the end of the week)

Only if you have no further use for an Oyster card...

or can I now put a 7DTC on my existing prepay Oyster?

Yes, you have been able to do this for some time. You can do it with
any Travelcard season provided your card is registered (I'm not sure
if they require you to register if it's only a 7DTC).

Just to add to asdf's answers - you no longer need to register any
Oyster card if it is for use with a 7DTC or a 7 Day Bus Pass
(prevoiusly you had to register in order to use an Oyster with a 7 Day
ticket but this requirement was stopped a few months ago). And it has
always been possible to have Pre Pay and a season Travelcard together
on a registered Oyster card, since the launch of Pre Pay in 2004.

So Rolan, you've no need for another Oyster card, simply put a 7DTC
onto the one you have already. If you want a monthly or longer season
on your Oyster card then it does need to be registered.

And perhaps you're not clear on one of the benefits of Oyster - the
ability to combine a season Travelcard and Pre Pay. If you need to
travel out of your Travelcard's zonal validity when travelling by Tube
or DLR then your Oyster card will automatically be debited the
appropriate extra fare - there's no need to buy a paper ticket
extension. And as Pre Pay fares on Oyster are cheaper than their
printed equivalent, you'll save money.

An example - you have a Zone 1&2 weekly Travelcard on your Oyster card,
and you wish to travel out to Heathrow on the Picadilly line from Kings
Cross. On arrival your Oyster card will be debited £1.80 (or £1.30
after 7pm and at weekends), which is the fare for travelling from Zone
3 to Zone 6. Voila - a ticket extension without the need to queue up an
buy one.

It should be noted that this 'automatic ticket extension' function only
works on routes where Pre Pay is accepted - i.e. the whole of the Tube
and the DLR networks, but *not* on the vast majority of the National
Rail network in London. For a list of the few National Rail routes
