Selectable in 1.0?

Team,
I found a couple of hints that Selectable is getting added to UI in
the 1.0 release. However, since they were only hints and Selectable
isn't on the main UI features page I assume that it probably isn't.
Can anyone say definitively that it is not? ...and if it is not, does
anyone care to guess at when it might be or when the next post 1.0
version is slated for release?
Thanks,
J
