Have any 10" stock Jelly Bean tablets been released yet, and do they use the Honeycomb/ICS tablet UI?

As we all know that in Jelly Bean, 7" tablets such as the Nexus 7 use a phone-like UI instead of the old ICS tablet UI, but what about 10" tablets? have any been released yet and if it's stock android, does the UI by default go to the honeycome/ICS style (because of the larger screen), or are google phasing out this style entirely?
