iphone 7 and iphone 8?

sung0015

I currently has iphone 5, and would like to wait for iphone 7 (I am in US). I heard iphone 7 will be out in Sept? Anyone know more about it?

However, I also heard next year, the iphone 8 will be made with glass. This sounds attractive. Would you wait for it and skip iphone 7? Why or why not?

Thanks.
