I think that Doog and friends bought far to much CLAMs on 0.0009 so we can't expect price increase. Beside that we have big inflation and constant threat of new digger. On the other fronts Just-Dice seems can't attract new users. CLAM is simple not attractive to them any more. You can lose twice on dice game and decreasing CLAMs with no volume.
Two years should be enough for everyone who wanted to sign up for CLAMs to do so. After that date new CLAMs rewards for every BTC, DOGE, LTC address should be drastically reduced or abolished.
