Mate I personally would just buy it. There is absolutely, nothing wrong with the nexus blade. We used ours for the first time this weekend. They are as fast as ****, and have the accuracy within a 10cm diameter from 50 yards away, and that is using training toroball
So the chances are they will just bring one out with different milling, i cant see any changes needing to be made to the workings of the marker.
But then again that is up to you mate, wait with no gun, or get a brilliant gun now!?
Choice is yours

Ps. We was training indoors so no wind. But it just shows how accurate the gun - to - barrel (DYE ultralite) is.
