No, they would NOT automatically lose their trademark, but they would lose some ground to fight on should they choose to take another person or thing to court over that trademark. So it's a balancing act.
So far they have been very very VERY lenient about doing only the bare minimum they need to, so far the ONLY things that have been actually told to stop completely, was MLP Online, which Given just how MUCH it used MLP stuff, okay might be a bit to much, and the one site that used to be up offering free downloads of the eps, which was up for quite awhile, and only got told to shut down after they started asking for donations.
You tube vids, they finaly went with the auto take downs, but that was due to China saying why should they buy the show right when everyone can get it for free. And even then, far as I can tell they've left season 3 alone.
So there's hope, and again, the big deal would be once it shows up on the main floor of EVO, if nothing for that, don't worry, and even so, byt then it will be done, once it is finished and released, no C&D can stop it.
