>I wouldn't be surprised if these new processors were unveiled about 8 and a half hours from now.
I believe that we will see the new processor architecture in the next Apple Watch, not the next iPhone. I think A9, that will be unveiled later today, will be an improvement over A8 but it will not be a radical improvement and will not contain a new ISA. It will have improved ARM cores.
Apple also doesn't require bitcode for iOS apps right now. They suggest you add them but don't require them. They're required for watchOS apps.
Once Apple starts requiring bitcode for iOS, within a year or two you can expect some radical Apple CPUs for iPhone/iPad.
