These are points I've wondered about too, but being I don't have a new bike I can't be of much help.
As far as the gas question, Suzuki claimed gas mileage improved when they went with the newer motor in 2012, which is why they decreased tank capacity. Gas mileage varies greatly with different people, so no use asking others. I would think you'd get the same or better mileage with the newer bike.
