Daniel asked the Naked Scientists:
   As the universe expands. Will the cosmic microwave background red shift into the cosmic radio wave background?
What do you think?

It all depends upon when space started expanding rather than mass simply spreading apart with a well defined velocity of its own. Therefore the hypothetical dark energy has to be important in formulating an answer to your question. If it in fact exists.
