Samsung shows the upcoming new NX lenses!

I was wondering why Samsung didn’t show anything new at CP+. But here they are the upcoming new NX lenses. Form left to right you have the 50-200mm, 18-200mm , 85mm f/1.4, 60mm Macro, 16mm f/2.8 and the Silver 20mm and 20-50mm lenses. You can find more pictures at SLRclub here and here. Those are all nice lenses but my question now is: Will there be third party lenses too? Sony and Micro Four Thirds just got the support from Sigma, Zeiss and Cosina. So will Samsung do everything alone?
