No mate, they are still going ahead with the 2nd gen Geo, this is just an extra - the 2nd Gen won't just be a Geo with this kit in either so don't worry
It solves the reball problem, and makes the Geo even quieter and softer on paint, whilst further reducing kick. They haven't said about it improving air efficiency, as this all depends on temp, ball to bore match etc which is fair enough
Mine is in the post
