Wait for pictures of the actual model, that just a drawing to show the paint scheme.
The last Kato CSX GE was correct so they already have the front and rear handrails.

"Multiple body styles to reflect different "as delivered" railroad specifications ".
GE 2005 also has the three vent DB, the only other AC ES they have announced so far that does.
