iPad 4 is running great on iOS 8. Was originally planning to upgrade but not sure, still love my 4. Flawless display, fantastic battery. However I kind of do want to upgrade - but will only consider it if there are two gigs of RAM. Knowing that the Air 3 will have the iPhone 6 form factor complicates things further though - I'd rather have that than the chamfered edge Air. But if I buy an Air 2, I won't upgrade next year when the redesigned Air comes out. So, are you upgrading from your 4?
