Apparently a commit made by Christian perrier confirms that Debian will use again Gnome Be Desktop Environment By default, although as much as I have searched I have not seen any official note that ratifies this decision.
On the one hand I would understand if Debian was a distribution of those that are dedicated to giving users an experience similar to the one provided Linux Mint o Ubuntu, But is not the case.
Let us remember that the developers of Gnome recommend using Xfce as an alternative for version 3.8, mostly when deleting the fallback session. Taking into account the number of architectures that Debian supports and that could conflict with LLVMpipe, I don't understand this new change.
Although in very real life, if we consider the development cycle of Debian, I think the next stable will come at most (which I doubt) with gnome 3.6, so there will be time to worry about those things later. If you ask me, I would say Debian could use Cinnamon before Gnome Shell Be Desktop Environment and the reasons are more than obvious.
There is another detail that I do not understand.What will they do to Gnome will fit on the Installation CD debian wheezy?
But putting that aside, the news does not displease me at all, since I think that having Xfce 4.8 default in Wheezy it would not be entirely beneficial, even less knowing that to improve the user experience, it would be more convenient to use Xfce 4.10.
