I'm thinking this is it for a bit. Quad core and 1080P and 5 inch phones seem to be the plateau for flagship phones (not phablets). After getting my GS3, I knew I wanted a 5 inch screen in the same physical size. And I know that will be my max. I will definitely be picking up a GS4 most likely and will hold on to that until the next real breakthrough. I also will pick up a Tizen device, as I believe in supporting new competition that has a realistic chance at succeeding. Now with the flood of all these quad core, 5 inch, 1080P phones coming from all over. Especially the devices from China, if they make it elsewhere and come in at a real cheap price. These units actually look quite nice, but I myself wouldn't trust one. I believe we're at a time, were Apple now has no choice but to change their model of small upgrades. The quick upgrade of the iPad is a sign of this. The model of one current phone with one screen size won't work anymore. With the massive success of Android and Samsung's rise to top mobile vendor, Apple knows it cannot sit on it's laurels anymore. Too many options with high end specs are now coming in at a cheaper price. People want bigger screens, we all know this from the research. And now that these bigger screens are coming in smaller overall form factors with minimum bezel, the small 4 inch display of the iPhone with it's thick bezel will begin to look very dated as it already has. iOS also needs a serious upgrade in looks and features.
