Yeah, you just get the box at the moment rather than the crosshairs over the eye.
I believe they'll be able to implement it though because of a few things:
* Processor being the same new gen processor in both S5ii and G9ii
* The eye box is technically already present on the S5ii - this was their first phase detect implementation so I'd guess the new functionality the G9ii has is due to development time rather than overall capability
* As the eye box is already present, I don't think it's going to take up too much additional processing power to write a display call into the code to make it visible to the end user.
That's the assumption of an IT professional though, not a camera manufacturer so take it with a pinch of salt. The good thing is, I have such confidence in the S5ii and it's ability to grab the eye, I don't need the comfort of seeing the box any more. If they do implement it, it's a nice to have but the thing just works. A really good bit of kit.
