Sure low end will dominate. Think of PC model. As PC technology matured, only few people need high end PC. Everyone can do everything they want on low end PC. Same is true with smart phone. Today's low end is defined by quad core or even octa core cpu, up to 2GB of ram and even an HD screen. One example I can point to is Xiaomi redmi S1, which cost only $130, but is arguably on the par spec wise with iphone 6. Not only that, camera on this phone is a great shooter too. And tomorrow's low end phones might be even better. Inevitable advancement and maturation of mobile phone stage will make "high cost" premium phones optional for virtually everyone.
