The devs are aware that many folks have an overabundance of Marks of Honor. They are in discussion about what Marks should yield, if they get turned in. The desire is there to find a sink for Marks, it is just undecided as to what will be returned for Marks or how the system will work exactly.

So, short answer is mostly 'Yes', with more details to come.

As something like this would most likely go into a patch, rough estimate would be post-TBC release, when we will start seeing patch updates again. The most recent patch will be our last patch until after release.
