With the strong rumors that Apple will release two different sizes of the iPhone 6 - 4.7 inch and 5.5 inch, would the go ahead and name them using the 6 and 6S designations. Might be easier for consumers when shopping for accessories like cases and other things that are size dependent. Or should they save the 6S label for an update in 2015. I got my 5S late last year (company provided) and find the idea of getting a replacement so soon difficult to justify, or at least not worth the paperwork. My eye's are getting older, so a slightly larger screen would be nice. I'll probably wait until the 2015 for the 6S, unless its clear that the there won't be a major update that year and the next will be an iPhone 7 in 2016.
