HK-51, Secret Companion!

Hello everyone!

During beta, there was full list of companions of all class. I was very intrigued to see that there was a HK, assassin droid as a bonus companions, available both to imperial and republic players alike.
He wasn't on the official companion list and even I'm not 50, I've never seen one having it around. So, I search on the internet and found out that even it's not sure that it's in game or that it is. Some people say that it's gonna be, either as a Legacy gift or after a long mission line. I search again and I found those two mission lines:

Then, last night I was in Hoth. While I was doing the planet's main story missions, I went across a interesting fact. During this mission'shttp://www.torhead.com/mission/63qbZzY/medical-advancement return, I gave to the imperial officers the core of an android that could think of it's self. I was thrilled! Was this just the beginning of the chain quest to acquire HK-51?

If you learn anything, please tell me!
