While there has yet to be an official statement released, one customer reports receiving an email from Discover stating that they have decided to stop charging foreign transaction fees made on international purchases:

We are pleased to inform you that, effective 11/06/11 we will no longer charge a Foreign Currency Fee on any international purchases made with your Discover® card. Additionally, we will no longer charge a Research Fee for any copies of billing statements or receipts that you request.

At this point, this news is unconfirmed. It’s also unclear whether this change would be made for all Discover cards or only a subset of them. If this news turns out to be true, however, it would be a very welcome development, giving travelers yet another credit card option for using overseas.

Where can you use your Discover card internationally?
It should be noted that international acceptance of Discover is more limited than other networks, so you probably won’t be able to use it for all of your travel.

Discover cards are accepted around the world through the Discover Network as well as through partnerships with China Union Pay, JCB and Diners Club International. The list of countries where Discover is currently accepted can be found here.
