Two off the top of my head:
1) Saga of Lucimia
www.sagaoflucimia.com
2) Pantheon
www.pantheonmmo.com
Whether they ever see the light of day, or whether they will be any good if they do, only time will tell. But they both follow the trinity and both are based on the more old school style of MMOs. So, they will be niche as people nowadays consider such things as 'antiquated' but for those who enjoyed older style MMOs, then they are probably the most likely candidates to watch - they are also PvE focused games.
