Yes, the Paris Air Show (Salon du Bourget), currently in full swing, and
traditional home base for many spectacular announcements, has indeed
witnessed this joint statement from Japanese and French interests. Of
course, they've put an estimated development schedule of 30-40 years on
the project, so one could be forgiven for feeling that, at this stage,
it's more big bluff than big business. But then, the A380 was first
mentioned there in 1985, and is flying public demonstrations today - so
the fact of making a splashy announcement at the Paris Air Show does not
necessarily preclude it from becoming a reality!

If I had to bet, I'll wager that Gulfstream does supersonic before
EADS/Airbus does.
