Oh, to be sure, I’m not suggesting there’s no market for it, but I’m not sure it’s necessarily aimed at Air 2 owners specifically - the original “Air” moniker back in 2013 was a name created at the time for a thinner redesign of their 9.7” iPad. Then the Pros came along, the nondescript “iPad” returned as basically an refreshed Air 2 (sorta), and the Air itself went away for a few years until they brought the name back as a modified version of the 10.5” Pro.
The “iPad” became the “iPad Air”, then it became the “iPad” again, and now the “iPad Air” is back alongside the “iPad”. Confusing!
The “Air” name turned out not to indicate a distinct product in the iPad lineup after all, unlike the Mini. Some Air 2 owners might have held out for an Air 3 for whatever reason, but it seems likely many of them just migrated to the Pro or the current 9.7 basic iPad.
In a way, it’s now just the midpoint in three iPad sizes all relatively small steps up from one another: 9.7”, 10.5”, and 11”.
The Air still seems like a more unlikely revival than the Mini, and it has a much more confusing identity than the Mini does.
