I was just thinking something earlier while sipping my coffee in Starbucks and reading about the newly released iOS 7 jailbreak. The iOS 8 jailbreak is going to be really difficult. Reason? Up until iOS 7, jailbreak devs have had access to the OS on a device with a known bootrom exploit (the iPhone 4) -- They can use the bootrom exploit to get into the system and learn about it, so they can find an exploit to use that will work on all devices, including later ones with non-exploitable bootroms. Most people are certain at this point that iOS 8 will not support the iPhone 4. This means it will be the first iOS released on a platform that has no available bootrom exploits. I'm sure they will eventually figure it out, but it will be MUCH harder to find holes in the system without this initial open door. So enjoy your iOS 7 jailbreak, folks. It may be the last one we see for a very long time.
