According to analyst Ming-Chi Kuo, Apple might introduce a cheaper version of the iPhone 5S at WDDC this year. The KGI Securities analyst has been correct with several of his analysis reports in the past, so we don't have much reason to doubt him this time. An 8 GB iPhone 5S will definitely lower the entry-point of a premium iPhone. However, this could only mean one thing. The iPhone 5S will take over the price slots currently occupied by the iPhone 5C once Apple goes official with the next-gen iPhone 6 models.
Kuo also says that Apple might give the world its first glimpse at the iWatch at WDDC. We'll wait for this one, as we don't want to get excited a device that has seen virtually no leaks in the past several months.
