Whoaaaaaaaa... hold on a minute there. you are comparing OnePlus with those phone companies? OnePlus is barely established this year! where HTC, LG, Motorola, Samsung had been in the market for 10 years+. the capital is different. you would have to look at the different point of view. at the moment, OnePlus would focus on GSM providers (which is the worldwide standard). you're comparing a market with billions of potential buyer on GSM vs just 200 millions tops on CDMA.
Again the keyword is WORLDWIDE. please remember that. Just because Verizon has the most customers in the US, it doesn't mean it has the most customer in the world. I personally have lived here in the States for 12+ years, and would never consider CDMA service. T-Mobile has been great where I live.
Now if I remember correctly, Verizon Galaxy Nexus was a joke anyway. OTA updates got delayed, bloatwares, etc etc. so I wouldn't even consider Verizon Galaxy Nexus a GPE device; it's just another Samsung Phone.
