Samsung's thinking seems to be that by getting such a phone rolled out before the end of the year, the Korean based manufacturer can come out of the gate first, before the Tegra 2 models that Motorola and others are planning to greet the New Year with. But is the Samsung Nexus S powered by a dual-core processor? Check out the tweet from Russian Tech writer Eldar Murtazin who writes that he is playing with the Sony Ericsson Anzo and the Samsung GT-i9100. Murtazin says that while the Sony Ericsson phone is nice, the Samsung model is "technically advanced" and features a dual-core processor.
So if this true, all of the speculation about Samsung wanting to beat the Tegra 2 phones to the punch would seem to be true. The only question left is whether or not Google was able to get Android 2.3 working with the more advanced chip-set in time for a 2010 launch.
If true,the Samsung Nexus S (aka Google Nexus Two) could be rocking with a Dual-Core processor when launched before the end of 2010
