It seems that the French and the Japanese have reached an agreement to
do a new version of the Concorde.  Details can be found in articles at:

As far as I can tell, this has been overhyped.

They seem to have actually reached an agreement to spend a million
dollars a year or so (each) on studies, for 3 years.  There isn't a
design yet as far as I can tell.  This is all slightly fuzzy because I
didn't find anything about it at, say, http://www.eads.com/ which
would be closer to the horse's mouth.

Here's an article which has the word "research" (which I take to mean
as opposed to development):

Here's one which says "With a research budget of less than $2 million
US a year over three years, the effort appeared tentative and
preliminary.":
