Lets lower your very high expectations so that we won't be disappointed if the keynote is a downer (Which I personally think it won't).
iPhone:
- No sapphire.
- Same resolution as the iPhone 5s.
/QUOTE]
Sapphire will be used for camera and home button, like on IP 5s for scratch resistance.
And no, for 200% the iPhone 6 will not have the same resolution as ip 5s. It's impossible, apple would never allow to lower so much the PPI. It's 0.7 inch difference!
I bet that the resolution will be bigger, but still below full HD. And if so, they'll make another bookmark in the App Store for IP6 like now we have iPhone - iPad
It's highly possible becouse if they don't do so, apps not optimized for IP6 will have black lines at top and bottom of the screen. (Like it's now when you download app optimiEd for 3.5 inch iPhone. )
As for RAM I guess that if they made performance tests and they were OK, we'll see the 1 gb of ram. Well, some ppl like to see bigger numbers, but if one gig will be enough for this device, they for sure won't bump the ram until 5.5 inch model OR iPhone 6s. Don't forget that iPhone is not android, and it is much better optimized.
