Will higher end panels eventually be using "Museum Glass" ? (Reflection Free).

Don't think "museum glass" is the same as Nippon's glare free glass that both Phillips and Sharp are starting to use. Nippon and Sharp have worked together to make their "MothEye" anti glare glass for large format displays. Should become the standard soon, even though other manufactures have their own anti-glare coatings, but they usually do not work as good.

Is Sharp's "MothEye" the same as Nippon Electric's Invisible Glass? I thought it was different tech. (somewhat disappointing if that's the case)

The isn't anything special with any "reflection free " glass. It is just an anti-reflective (AR) coating added to the glass.

Very similiar to what is used on prescription eyeglass lenses, such as Crizal Avance, Crizal Sapphire, Kodak Clean and CleAR, or Zeiss AR.

Each AR coating has its own "formula" with various attributes - light transmission, scratch resistance, etc.

In eyeglasses, other attributes are important as well - cleanability, adherence to lens material, etc.

What's special is how low the reflectivity of the glass is - Nippon Electric's Invisible Glass reduces luminance reflectance to just 0.08% for example, using 30 layers of anti-reflective coatings, compared to typical AR coatings which use 5-8 layers on one side of the glass.

I could definitely do with less reflections/glare on my Crizal Forte coated lenses. Cleanability is not really an issue for me as I just drop them in an ultrasonic bath rather than use cleaning cloths.

I think you maybe be right. I knew Nippon Electric had a their version "invisible glass" and read Sharp partnered with Nippon to make the film for their TVs, but apparently they partnered with Dai Nippon Printing to make the Moth-Eye film, not Nippon Electric. Unless it is like a subsidiary company or something.
