Notably, some pens support additional pressure axes (for example, the "brush pen"). These are general-purpose sensors can be mapped freely.
I'm not aware though of any pen that supports truly 6 axes, but I suspect it's not a technical limitation.
[edit] I actually dislike the art pen because of the way it's handled: it's too fat.
One trick is to use the eraser as a tip and to cover the tablet with a neoprene skin stretched tight. The result is a really light and spongy stroke. Has a very sensual feel.
Tried it once. I suspect that if you spent thousands of hours drawing that the haptics would make a difference.
