In a recent developer meeting (2015-06-14), Ton mentions alembic as a possible addition in 2.76. Lukas Toenne has been working on adding alembic to blender for some time, you can checkout a copy of the alembic development branch and build your own copy of blender if you want to help test.
So yes you should expect alembic support in blender, later this year would be a good bet.
As alembic was developed by Sony Imageworks and LucasFilm to handle transferring data in a commercial film production, you can expect it to be well supported and tested. With two big names attached to it you will find other film studios willing to make use of it, making a common industry format that will most likely be widely used in the future.
With alembic being a recent project it has the benefit of looking back on the 10-20 years experience of using obj and collada and designing around the issues that have existed before.
