Yesterday we were confirmed that for iOS 7 there is a method of jailbreak, this being the first confirmation made by any entity that has non-public exploits for iOS. The proof published yesterday gives us confidence that in the future we will have a solution of jailbreak available for our iDevices, but probably few were circumspect about this, especially since releasing a jailbreak solution for iDevices is a very profitable business that hackers will not abandon too soon and too easily.
Even if it can be done jailbreak pe iOS 7, for now it is dedicated only to application developers and hackers looking for exploits, the jailbreak being most likely a tethered one. Cydia is not compatible with iOS 7, the tweaks and applications in Cydia are not compatible with iOS 7, so you have nothing to do with this version of the operating system for now, even if you could jailbreak it. Now to answer the question in the title, a jailbreak solution for iOS 7 will most likely be released sometime around November/December, at the earliest, but in the worst case, we could have it available at the beginning of 2014.
To be honest, no matter when the hackers release it, they will make money and the world will be happy, but releasing more jailbreak solutions will attract more money, so maybe they will be motivated to release more iOS jailbreak solutions 7.
