I'm looking for a good projector for a windowless room.

I currently have an order in for an epson 5050ub, but having 2nd thoughts. Contrast is important, and I want something that will last me a good long while. I've had my current projector since 2008, so it is long due for an upgrade. Is a projector from 2019 worth it? Are there new profits scheduled to come out soon that would have the high contrast but also have HDMI 2.1 at the <$4k price point?
