Really good video. It appears as though they took a page from Ebonite's book with the videos of the ball with a different coverstock finish. Overall, though it looks as though its a great ball. It looks to me actually like a higher hook potential Ambush.
As for your question, Noy, yes and no. They are basically saying that since lanes strip the lanes so often, many times the backends are fresh and thus, an earlier rolling ball, a ball with a lower rg, is more controllable, less jumpy at the breakpoint (as opposed to a ball that maintains a great deal of energy and releases it all at once).
Also the Activator is a longer cover than the pk18, formerly on all BVP releases, and thus, they need a earlier rolling core to offset, somewhat, the late hooking activator coverstock. We have seen examples of balls that have had Activator and elevated rg's in the Blazing, and Intense (+) and such a reaction doesn't work for a lot of people, and results in less successfl balls. I'm personally mildly surprised that they went so considering that they are using a high load particle version of the activator. Such is probably why the polished version looks a bit better than the sanded.
Saying that low rg's match up better to modern lane conditions is a little misleading though. There are certainly places for elevated rg's, when the lanes break down, playing in friction areas, and a few other instances. A lot of the focus on lower rg's has come from certain heavier lane conditions, in many instances sport shots and tournament shots also employ a heavier patterns, though they are not obligated to. Also a shift to people employing more hook, has certainly made hooking balls greater commercial successes than less agressive pieces.
