I'm definitely interested in getting the GR07s because it definitely came down to that or the Ety HF5s, but as I've stated before, I did go with the Ety's just because of the none confusion with the different versions of the GR07, as well as the overall consensus over the Etymotic HF5.
I don't have the resources now, but I'm most likely going to be purchasing a GR07 in the future, if anything else close to it doesn't come out. But I do plan on getting the CCE version, or the MK2 if it is still available, as the BE ones you linked are out of my price range.
