2nd question, isn't the N20 a brand new engine? Why are they already ditching it?
3rd question, is there any significance between the 'N' designator and the 'B' designator in the engine name?

Why are they ditching the N20 already?
The N20 is based on BMW's N-series engine modular design, so while the configuration (4-cylinders) is new, the modular design on which it is based, is not. My interpretation is that the N20 was a stop-gap engine. BMW had to move away from the N52/N53 because its fuel economy and practical performance (read, low-end torque) were being outdone by competitors.
What's the difference between B and N?
Better specific output capability, lower emissions and better fuel economy. That I am aware of, BMW are not introducing any significant new technologies with this engine. Rather, it is an evolutionary step forward. I'm sure if I'm wrong about that one, someone will be along to correct me shortly
