Summer starts in June (21).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.
We were seeing iPhone 5s parts earlier than this last year. It still came out in September.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.
