Is there already a big loss of players?

I am on the Xbox and I haven't noticed any drop. I seems like more people are on. Also that seems normal for any game now a days on the PC. There is so many games and not enough time in the day to play them all.

I have quite a few friends that have since quit Defiance due to the bugs/lack of content. Some will be back after it's fixed/expanded on.

I did an entire arkfall last night on my own, not a single player showed up. I killed over 350 hellbugs when usually its like 20 , it was very lonely.

Most MMO's experience a decent drop in player count during the launch period. Thankfully, it has not dropped to a point that I find to be noticeable.

Considering the amount of sharding, phasing and instancing, it's impossible to tell.
