Full roster minus one coming to the org, klanton no longer playing with this team apparently, he posted in the Reddit thread elaborating on the situation:
"We had an internal discussion whether I should keep playing in the team or not. We mutually agreed that I would step down for now. I'm still going to play but it's not deccided where and who I'm going to play with as for now." source
Doesn't seem to be any indication of who will be stepping in to fill his shoes.
Makes some degree of sense as a move I suppose, SK have of course had experience and success with an all-Swedish lineup before in 1.6 and I'd think the other big orgs that will be on the hunt for Swedish/Scandinavian teams (e.g. NiP, Alliance) can easily afford to wait for the scene to settle down and establish itself, see if expanding into Overwatch is something they wish to do and then cherry pick their own rosters if they want them; I doubt contract buyouts would be any real issue for NiP or GoodGame if it came down to it. Considering their org hasn't really had much properly notable success in recent times I'd imagine SK don't really have the same luxury, could be wrong of course.
Still, fun to see an old-school name like SK jumping into the mix so early on.
