I just did the first 3 story missions. No talking or sign of my ghost. Must not have wanted to pay Dinklage to do more voices so they conveniently forgot about the whole ghost angle.
When I turned in my 3rd story mission I got a new legendary sniper rifle called Murmur (which apparently everyone gets but it seems pretty awesome to be able to choose what type of damage it does - arc/solar). Also turned in a blue engram to cryptarch and got the new warlock vanguard helm (str one, but at least I can use it!). Either I got lucky or they tweaked the legendary rewards up a little bit.
