SK-Gaming gave their Counter-Strike Female and Counter-Strik Source teams the boot in late 2010 and promised to focus more on other big titles.
The twitter entry should be considered a PR move and not a leak.
SK-Gaming had a very successful Korean WarCraft 3 team, but with roots in the European scene. Time will tell which region they will pick from.
Nothing has as of yet been revealed on the SK-Gaming website.
