Glad, amazed by my iPhone 5. So no, won't be happening for me. I always skip the S (3GS, 4S, 5S...). Still looking firward for iOs 7, my fingers have never been crossed so tightly together 
iPhone 5S
Faster processor
Better camera (13 Megapixels? with new flash)
Fingerprint scanner
Lighter
Thinner
iOS 6
New colors

If you have time please post why or why not.
But, there's no need for 2GB of RAM; there's nothing the iPhone can't do that would require 2GB. (The only reason the Samsung GS3 and other Androids have 2GB is because Android is so laggy)
Phones don't NEED Dual Cores, quad core graphics, LTE etc. It's called advancement in hardware. As time goes on and software gets more advanced specs get better. And in order for apps to get significantly better then need ample hardware. Better specs are also a selling point. Why doesn't the iPhone still have 256mb then? The bolded is also false.
No, the bolded isn't false. The 2GB is needed to power TouchWiz. Not only that, there's no major benefit that you can't have with 1GB. Not only that, the iPhone 5 has 1GB of RAM, the iPhone 4S has 512, so your claim is false.
Android *IS* laggy, and the S3 has lag. In the time I got to use a Galaxy S3 (Around a Month & half), it wasn't unbearable lag, but when compared to the fluidness of the iPhone or even Samsung's own Windows Phones (which I do somewhat like), it had very noticeable lag launching programs, even just swiping pages of apps. It's not as bad as I had on my Nexus 7 at times, but still not perfect. Better specs are a selling point, but that in no way at all means a phone is better or even sells. The Sega Saturn was more powerful than the PS1 and the Nintendo 64, but it had horrible sales figures. The iPhone 5 is not as powerful as its competitors, yet it still comes out as the #1 sold phone. Don't associate powerful specs with sells and quality.
