I don't know why everything thinks this is all such a big deal. To those who are going to buy the Viper, they weren't going to buy the Galaxy. Sprint isn't heavily advertising the Galaxy Nexus, because it's niche has the smallest impact of the entire lineup, current, past, future.
You all need to take a marketing course or something. The G-Nex ISN'T a mainstream device, isn't going to make or break carrier sales, never was, never intended to do so. It's just "another" option.
Mainstream is Galaxy S series, Mainstream is HTC flagship. BTW, the G-NEX, is NOT a flagship device! Mainstream is also price point, and anything under $100, is mainstream!
Mainstream = carrier focus, period.
The G-Nex could be released right now, and no one would KnoW about it! Sprint just doesn't care, and they don't need to, as it's not going to make or break them.
Samsung ALSO could not care less. They have millions of Galaxy S series devices moving out of their doors by the second.
LOOK AT THE BIG PICUTRE - AND THEN UNDERSTAND IT!
