So they can't get the GSO out which is why the SK series were going to be made yet not a single one has shipped yet so now they are going to add another line of blades that "should ship" in 4 months time. Yea the SK series were suppose to ship withing 8 months and nearly 3 years later not a single one has. They also have add several new models to the line too. Oh and get this if you are tired of the GSO wait then sign up for the SK series which is the same thing but they are going to say when you transferred to it then you'll have to wait just a tad bit longer but not as long as for the GSO line. All models are in production but 3 years + for GSO 5.1 and others have not started. Yep keep sending them cash folks and someday when the sky is purple and the dragons from planet Guy comes by you'll get your blades.
