Their was an article in Astronomy Now last month saying the same (about the ISS).

I understand the logic behind the thinking as it wouldn't make a good base on the way to building a moon base as the US now wants. For the rest of the countries involved in the project the ISS no longer seems to have a huge purpose. Most of the scientific data about the prolonged effects of zero-g was gathered from Mir and many of the other scientific benefits are also seen as irrelevent now.

I'll try and find the article later and sumize it. Basically though it suggests decomisioning the ISS.
