Hmm, remains to be seen if they will indeed go for the folding tails. Though, if the stealth impact can somehow be managed, that'd probably make a very efficient solution to takeoffs/landings.
I also expect the intakes to be different, with simpler lips and possibly starting more to the back.
And I definitely don't expect that many cranks in the leading and trailing edge of the plane. The image seems to have a slight crank at the leading edge, near the nose of the plane. Plus the trailing edge, around the engine exhaust, seems either to be curved or to have two cranks... Too many.
