As the question states, is it just the Air that has IGZO? Or does the mini have iGZO too?

Now how would we know that? It's not even confirmed that the Air is using IGZO tech.

I really don't think they could have done the mini without using IGZO technology , so yes I think it will. So far the Air looks pretty, and pretty much the same as the iPad 4 but uses less power.

It pops more to me and looks better than the previous gens.

The iPad air lost battery size, but retained its longevity. The Mini is gaining a serious increase in battery size in order to keep it running as long. I know the Mini is doubling resolution, but with a supposed 57% power saving from an IGZO panel, and a power-efficient A7, I can't reconcile why the Mini would still need 45% more battery to last 10 hours on a charge.

Where did you find a 45% battery size increase on the Mini Retina? Apple's site lists iPad Mini 1st gen with a 23.4 Whr battery and Mini Retina with a 23.8 Whr battery. Battery size is nearly identical. The thickness increase is most likely from the display panel.

Meanwhile iPad Air dropped from 43 Whr to 31Whr.

My guess is that they are both IGZO, because there is no way the A7 is efficient enough to drop the battery size that much in the Air.

The Original Mini actually had a 16.3 Whr battery.

Hmm, interesting. It seems you are correct looking at reviews, but looking at the $299 mini at store.apple.com lists this under tech specs:
Built-in 23.4-watt-hour rechargeable lithium-polymer battery
Up to 10 hours of surfing the web on Wi-Fi, watching video, or listening to music
Charging via 5W power adapter or USB to computer system

Did apple silently increase the mini's battery capacity? Or did somebody make a typo? It is weird because it is 23.4 versus the retina at 23.8...

It's not listed everywhere, the Apple Store app for example still shows 16.3 Whr, so it's most likely a mistake. Whatever the case, I still question the inclusion of IGZO tech if the battery needed such an augmentation.

Even if you improve the efficiency of the light source, the Mini still needs to drive a screen with FOUR TIMES as much resolution as the old model. That takes battery power no matter how you slice it.
