I agree, Apple very rarely releases a completely revolutionary new device or upgrade, they have found that if you build hype around smaller improvements you can sell just as much. If they released all their tech improvements in one device then that would raise the bar for their next release.
People always start to expect more than what's reasonable. If Apple releases everything at once, then peoples expectations for the next release will be more improbable and outrageous.
Personally, I'm waiting for the day when your phone becomes a key for everything, using close proximity tech, not unlike our Z key fobs. When you get home, your phone detects your garage door opener and activates it. You get to your front door and the motorized deadbolt detects your phone and automatically unlocks. Walk up to your car and it unlocks and turns on for you. And of course using your phone as a credit card has already been possible in Japan for years.
If Apple were to implement all these things in their next phone they would not be able to handle the demand in sales, but then when the next phone comes out the masses will be expecting something just as big, and tech isn't developing this quickly. The next phone would be a huge flop.
