so is there any word on what the 3rd dlc will be since alot of us caught onto heartthfire before irs announcement?

Dawnguard and Harthfire were only discovered by the trademark registration. Their actual content wasn't known till their official announcement

Be patient and watch the forums and Bethblog. Rumours are just rumours and do not constitute fact, so no need to start worriting about the next DLC. It'll come when it comes, just enjoy the game.
