June/July iphone 5S wheres ios 7?

I know there are tons of rumors going around that apple is looking at a summer launch in the June/July timeframe but if that's the case wouldn't there at least have to be 2 to 3 months of the betas of ios 7? And if they plan on launching it in July that would give them one month after showing it off at WWDC it just doesn't seem like that's a way they would go. I think they are going to stick to September any thoughts???
