I'm a nike tester and last summer they gave me a pair of the new 4.0's to test. That new mesh with the vertical lines is actually very comfortable. Its very stretchy and soft, doesn't irritate your skin or cause blisters. Doesn't crease either. Its very elastic-like in that it stretches but always returns to its original shape and size. Aestetically, I don't think it looks as good as regular mesh, but performance wise, its an upgrade for people that actually run in them. I don't like the exposed flywire look on the FR4 either, but hopefully the ID options are extensive.
Also, from looking at those ID promo shots, those look like the regular mesh like last year. So maybe on ID you'll have the choice of which mesh to use.
