If the original mini doesn't receive iOS 8, it would have the shortest support lifespan of any iOS device, as it would've only received one upgrade. There is no indication that it will be cut.
The 4S, original mini, and 5G iPod touch are very similar. And given that they are all still on sale, I expect they will all receive iOS 8. Even though the iPad 2 is technically similar, I don't think it will get the upgrade because it already received three software upgrades and is no longer on sale.
The real question mark is the third generation iPad. It could easily go either way.
