Yes it has finally happened, after 4-5 long years, bmesh is now merged into Trunk 
so any builds on trunk will now be using bmesh and the next release will be bmesh based 
http://lists.blender.org/pipermail/bf-blender-cvs/2012-February/043451.html
this will also mean that the next release cycles will be longer then normal to make sure bmesh is both stable and bug free(ish)
congrats to everyone
