There are two different types of TFA TIEs seen so far. You guys seem to be talking about the so-called "spec ops" TIE. Most of them, as seen in the trailers, are just the normal OT-style TIEs, painted black.
No, the TFA model is different, imagine the spec ops model but without the wheel-like protrusion on around the solar panel roots.

IIRC the Tie Advanced sported the same rear window during the cockpit interior scenes, continuity error?
