How are they planning to get the present space station crew back down if the Russians can't fix Soyuz?

There are presently two Soyuz craft docked with the ISS for crew departure purposes. However, they have a limited time they can remain safely rated for use in space due to an expiration date of 200 days. Beyond that the type of fuel (hydrogen peroxide I think?) they use begins to deteriorate.
