All it suggests to me is that there is a lot of money to be made from pageviews.
Highly doubtful they would launch the new phone without iOS8 which won't even be unveiled until June.
I noticed the trend for parts to come about 2~3 months before the release.
With so many parts showing up recently, it suggests the 6 release will come earlier then past.
what parts? I dont remember seeing 5s parts until june/july
