Will new iPhone software need new hardware and more Ghz oomph

Well there you go iPhone users two years down the line you get cut copy and paste, but hats off to Apple the phone is really at a tipping point of functionality when it come to different usage and they have probably made this stuff work better by waiting.

I do fear though the lack of things like flash support really means this summer we will have a new iphone probably same form factor but a lot swapped out under the hood just to drive all this stuff it can do faster. How long will it be until phones have a Ghz rating - actually come to think of it why don't they have one now ?
