I doubt it. The rumours about A5 support have been massive.
Theres no reason for any one A5 device to be dropped. They either all get support or non do.
Mini 1 = iPad 2
Touch 5 = iPhone 4S
iPad 3 = Marginally slower than iPad 2.
The slowest A5 device is probably the 4S, which makes no sense to drop as 1. Its identical to the Touch 5 that is bound to get support and 2. It has been showing up in logs as running iOS 9.
The iPad 2 is probably the fastest A5 device, the same as the Mini 1 as it has a higher clock sped than the 4S/Touch 5, and if the slower 4S/Touch 5 can run iS 9 the iPad 2 should be able to, not to mention that if the iPad Mini 1 can run it (most likely since its still for sale) there is no reason for the iPad 2 to not run it.
The iPad 3 is slightly slower than the iPad 2 (both in observation and benchmarking, as the retina display was too much for the A5X. However, I don't see then dropping this if the year older iPad 2 gets support, so I'd guess the iPad 3 is in as well.
If Apple has gotten a specialised version of iOS 9 working for its older devices, there is seriously no reason to leave any A5 device behind, especially given the iPad 2 has the highest installed base of any iPad to this day.
Never thought I could take hours to try to understand what everybody is saying, and what the opinions they have.
I still have this idea: if apple want to run their businesses, they should never try to drop A5 chip support so suddenly, as long as they still sell it, and more important, more users with not enough money to buy the latest has purchased their maybe first apple device.
Apple is far from ready to enter enterprise market as Microsoft has already done. IOS is for now, definitely not a good OS for productivity. You may blame me for that but if apple take no action to optimise their iOS, they will have fewer enterprise customers.
For example, let's say users are using a productivity app, without crash recovery. If users switch to another app, do something, and switch back, they surely hope previous app is still there. But if it reloads itself, and everything not completed is gone, what would users think?
Not all, even enterprise guys want to upgrade to the latest and greatest, except their device is broken or stolen. I bet lots of companies buy iPad for employees just want them to do lightweight jobs on the go. Heavy lifting should be PC's job, not iOS job.
I don't know what Steve Jobs thought about apple. Maybe he wanted to create apple as a high end brand, only for guys such as movie stars. But now, Apple is so popular (especially in China). Then apple is no longer able to just meet die-hard ideas. Yes, they still need to develop new devices. But they also need to step back, and make some wrap up for old bugs. This is great for human society. And I am sure this is also great for apple.
I have so much to say. I just want to say later.
