Model Railroading > Walthers / Mainline HO ES44AC's?

Has Walthers' provided any updated info on their soon to be released ES44AC's, such as pre-production or production samples of their soon to be released ES44AC's? Their website shows an expected delivery date of 28 Apr., 2017 and the images on their site are the lettering artwork and 3D isometrics for the diework.

What I am looking to see is if they are going to correct the NS model where the front door has a window and the UP units do not, as well as what variant of site glass they are using on both schemes. Also, if anyone knows, the 3D Isos show both NS and CSX with the narrow western style handrails at the stairwells, not the prototypically correct wide versions NS & CSX still use.

Thanks for anyone's insights.

Regards,
Russ
