Is there any word on when the new Home, Pedigree, Person, etc. pages will become permanent?
who is "we" ??? (who are you speaking on behalf of)
Surely it will become permanent at some point in time - its just a matter of time. But I doubt that they may have a concrete date because they want to be flexible as to how people are responding to it - and allow time for adjustments and tweaks and allow users to adjust to the new format.
@Liz ., further to Dennis's excellent points, if there are specific things that aren't working for you on the new detail page, and you have suggestions for how to improve them, please join the New Person Page group and post your comments and suggestions. There are product managers and engineers who keep an eye on that group; they have implemented quite a few of the suggestions that people have made, and fixed the errors that people have pointed out.
