It has nothing to do with no player models or delta coming soon, Jailbreak itself is just dying. There is literally 18 people in the entire playlist atm (at least from what i am able to load). We consistently got more then that on our servers before. Gmod itself is experiencing a huge dip in players atm. Adding new player models or revolutionizing the gamemode wont help the fact that its a dying game. It may prolong the enevitable, bring a minor spike in users, but all in all it gmod is on a downward slope. Maybe once christmas break comes along people will be more inclined to play but currently gmod is dying.
