"WP8 is likely to have its own set of minimum system specs.
But I would guess that there would be some sort of update that adds in similar functionality. It's my guess that WP7 and WP8 will simultaneously exist in the market for a while."
What you're saying is that there will be wp8 and wp7 that has exactly the same features but different code, and can't run most wp8 apps lol..
Sorry but I definitely dont agree, and hope Microsoft is smarter than to start down that sort of road
Start down what sort of road?
It's called a transition. The kernel used in WP7 isn't ideal for future growth. Once that is changed, the transition is done. WP9 will not have the same issues because it will be updating from an OS that is based off of the same kernel.
And what would be wrong with continuing to sell WP7 devices for the next few years as economy smart phones? Why is that "stupid?" Because I'm beginning to think that you're trying to insult me.
You make the mistake of thinking that the process I'm outlining would be the process for all future updates. But that is not the case.
If MS really does have grand plans of integrating multiple platforms, then the transition to a common core does have to happen some time. Whether it happens for WP8 or WP9 is the question. But it will almost certainly be at a x.0 release because it is more than just an update.
What I'd like to hear from you is a well thought out argument about how you believe such a major transition should take place. And in a way that is technologically feasible while also moving the platform and the whole ecosystem forward.
Calling a transition stupid without detailing a better alternative comes across as a little whiney.
