>I don't see how the ones on the leaked pictures are significantly worse than the rings on the current Touch controllers.
They're literally the same rings. Have you actually used a WMR before and a Rift S? The size difference is immediately clear. WMR is still Vive-tier levels of controller banging into controller/headset. 
Also they better have removed the need for two AA batteries, per controller. 

>Do we know for sure there isn't one on the top? 
We've already seen what the top looks like. There is no top camera.

>They look really close to the Rift S other than that, so I don't see why they wouldn't copy that too
Almost, but not quite. Rift S' cameras are oriented more on the corners, so they have a better time looking downwards. This helps massively in FPS games. However even Rift S' controller tracking in FPS games is not perfect and if this headset has the cameras oriented even less toward the bottom then it's going to suck more.
