The newest version of the arduino was announced last week. At first glance it seemed as though they got rid of the offset header spacing, but a closer look at the spec showed that it is still 0.16 inches. It would have been a bold move to change that spacing; there are a lot of 0.16-spaced shields out there. Looks like Sparkfun will be selling offset headers for some time to come.
