For that you’ll have to wait a really long time. 2.5 will not be ready during the summer - we’ll have a 2.46 first, then start with the difficult event system refactor.
Concerning galleries, perhaps there haven’t been any entries sent that are worth it to include to the galleries. I think people misunderstand the purpose of the gallery over at blender.org. It is not there to showcase the artists - sending in entries doesn’t automatically mean you get accepted either. Instead, the gallery is there to promote Blender. I think there has been talk about changing the naming of the gallery and drop the month part from it, to prevent people from thinking this should be updated every month.
