The major differences/new stuff is that they will have

New 22 series & X-cutters...slightly weaker in spine & lighter in weight

New "ultralite" series of arrows in 600 to 300 spines, IIRC

XTs & Hunters will now be +/- 2 grains instead of +/- 5 grains

New graphics, and Hunters will be cleaned at the factory

Big Game Arrows will drop to +/- .005 straightness tolerance from .003 previous.

Personally I'm glad to see the weight tolerance tightened up on the XT's. But Goldtip really needs to work on ID tolerances..I nearly broke over my knee every GT arrow I had trying to get my broadheads to spin straight on them..sloppy tolerances in that realm....

They are not there yet, but getting closer all the time.
