I killed a wave of them just to be sure. Jagex has mentioned released some rares through community events.
They're not going to release any rares until the summer.
I noticed that, with the goblins just east of Varrock, the wood it bots seem to get attacked by multiple goblins.. Hey it could be one of their anti bottling things? But other than that, it's quite pointless but nevertheless it's quite entertaining for people skilling etc within the banks.
you can't even get xp from it so whats the point?...
