Sketch doesn't yet support PSD. PSD format is a little bit of a complex format to support. However they have made it clear that it is a very high priority on their list several times. So it will come eventually. It's more of a Fireworks or Illustrator replacement then a PS replacement. It doesn't come with all the lovely filters and stuff PS has. It also doesn't have the complexities of Illustrator. But if you are a web developer, it has some of the best tools for that specific development. Icon design, web design, buttons, etc. are all a snap to create.
