The latest rumor suggests that Sigma will announce the 17mm f/4 DG DN, 50mm f/2 DG DN & 23mm f/1.4 DC DN Lenses within the next few weeks.
Since the 17mm f/4 and 50mm f/2 are compatible with magnetic metal caps, they are probably I-series lenses with metal barrels and a high quality feel. 23mm f/1.4 DC DN is an easy-to-use prime lens, so I think many people have been waiting for it. Pricing and release date are unknown at this time.
