Yes looks like they pretty much replaced the old line , although only the 50 1.4 and 85 1.4 are new designs. Better wide open which actually both of those lenses needed anyway was better 1.4 performance. I think it's great even for Sony owners as well as its just more lens choices we can use as we wait for certain focal lengths to come in either the Loxia or Batis lineup. All good IMHO. Myself I'm pretty much all set although we all want a new 135 for instance and some wides but still very good idea for Zeiss to update which looks like going forward new lens body designs. For Nikon , canon landscape shooters heck I would order the whole line up.
Personally I wish having the two Batis lenses , I would buy a whole lineup of them myself. Hope that will happen soon and I will just keep replacing lenses till I have the whole line but we get AF with Batis so a nice bonus.
Here is the beauty of owning Sony is they will make AF lenses , Nikon and Canon we will never see that because of licensing agreements so IMHO a advantage for owning Sony
