Yes, and that's exactly the problem Brunswick has created for itself. Why buying a symmetric new Inferno when you can bet that the coverstock will become available in half a year on a asymmetric Zone core.
Personally, I think the Vapor Zone is for example a very good ball - anyone I know who throws it LOVES the ball. Players can be happy about it. But, strategically and from a marketing point of view, I think it was released much too early (regarding of the rest of the line up), unnecessarily cannbalising on the AI. I was also wondering when they released the ZC and had the OI going parallel - also too early IMHO, but probably under pressure of other manufacturers and with the PK18 TZ and WZ around which were not really state-of-the-art, just med-price balls with a new asymmetric core.
Whatever Brunswick has in the pipeline for high performance, it better be something impressive and setting itself further apart from the Zones, with some true arguments to buy such a ball and not wait for its components to show up a couple of weeks later in a "lower" rank ball.
