In mailing list of developers Debian has been announced by Neil mcgovern, that debian wheezy (aka Testing), it will go into the freezing phase (freezing) next June 30, that is, next week.
Everything seems nice to me, except that there is something that worries me. When you go into the freeze phase, new versions of packages are not included unless it is for something very necessary. In matters of Desktops, already in Debian Testing we have complete (or almost, I'm not sure) all packages of Gnome 3.4, the packages of KDE 4.8but my dear Xfce 4.10 it's still in the Experimental repositories, as they haven't even passed it to Sid.
So nothing, to wait to see if for the next version Stable de Debian is included Xfce 4.10, although in truth, I will always use Testing 
