Sure, didn't say anything about that. A hole in the middle would be fine. Personally feel like the useless pixels between the hole and the bezel would bother me more than just having the regular old notch, though.
So yeah, if they manage to make the sensor array and whatever in the notch considerably smaller, I personally hope they just go with a smaller notch for XI, rather than any sort of punch hole situation.
None of this matters that much, though, since my next iPhone will most likely be an XS when its price comes down a bit.
