Pixel starts at $649 (USD) and coming to Bell, Telus and Rogers. Nothing said about MTS. In the US it is a Verizon exclusive.
Based on other carriers/Google Store:
Pixel 32 GB $899
Pixel 128 GB $1029
Pixel XL 32 GB $1049
Pixel XL 128 GB $1179
Current colours are Black and Silver. There was also a blue announced but it does not appear to be up anywhere.
So there is a cost.
Only thing that I'm holding out for is... Black Friday sales... Whoever has the best deals will keep my business. :) and then I'd consider staying with a Samsung phone. But if the prices remain the same... I'm probably out of here.
