A look at history
So, when I like in the Macrumors archive we see this:
2012: iOS 6 first showed up in March 2012. The new iPhone launched in September. Five months between discovery of iOS 6 'mentions' and launch.

Looking at history...
Counting this month and looking at past launch patterns, than a new iPhone should launch in June.
Of course, this is all speculation, but the fact that iOS 7 shows up this early could indicate that a new iPhone is going to launch sooner than we anticipated.![]()
Your historical analysis actually shows the gap as 6 months.
This would be one hell of an observation if you're right. Guess we'll find out soon!
