The next batch should have AR and we expect to offer replacement panels for existing owners at a discount.

Don't take this the wrong way, but why should existing owners have to pay to get the AR coating that should have been on there the first time? Especially considering many of the first owners were MkI owners, or were familiar with the MkI, and saw it had an AR coating, so it was reasonable to expect the MkII would have one as well.

Personally, I think the existing owners should get their AR panels comp'ed, and I'd say that even if I wasn't one of the existing owners.
