New Kato N AC4400-What's the difference?

Katos new N AC4400 looks pretty good, but what’s the difference between it and earlier AC4400s from Kato?

If Kato’s site accurately describes it, the position of the number boards has changed from “high” to “low.” I don’t see any other differences listed, but the way they have them described makes it hard to compare.
