As a type 2 diabetic, that would be a great feature to have, but glucose monitoring does require a needle to be in the skin. There are already products on the market (Dexcom comes to mind) that already work with Apple Watch.
Now, with that being said, I do not qualify for Dexcom because not on insulin so if Apple does come out with a GMS I just it's affordable as I'd probably buy it.
A pulse ox would be my guess for next monitor.
Pusle ox is fairly simple. 2 LEDs, one red, the other IR, and the sensor. The problem is getting FDA (and similar non-US agencies) approval. Since they've gained some experience getting their ECG functions through they must know how to get it done.
Apple's head of medical research used to be the head of Masimo, a big maker of pulse ox meters and sensors.
Great info and no doubt much more likely than a non-invasive BG sensor.

Can they change the color of the existing LED to be able to read Pulse OX with a software update, or would that require a redesign of the LED array on the back of the watch?
They could do it with the old (Series 3 and below) and new one. They would have to change the LEDS to red/IR and probably redesign the sensor but it wouldn't be a big lift. The expensive part is buying the detection algorithm or making their own to determine the O2 saturation. And they'd need additional FDA (in USA) approval. That's why the ECG rollout was so slow. Getting the various governments to approve.
I would think this would be a lot easier than monitoring Blood Sugar levels, but then, who knows.
