It's unlikely that they will put in pure deathmatch options. Its not really what the game is about.
How is what's there now more boring than team deathmatch where there is less to do?
Currently every mission is a team deathmatch to fight to the objective and complete it. Then theres another round of team deathmatch to get the the next objective.
The defenders play team deathmatch for the entire round.
Also: What stats do you want? I doubt there will be "regular" shooter stats like K/D ratio since that doesn't really fit with the concept either.
