Ultimately I personally think there's an enormous amount of hype and hoopla about a product from a very small segment of consumers, especially considering the notable degree of unavailability across the board.
Some will obviously point to Titleist's alleged legal action being taken against the manufacturer regarding patent infringement to make an argument that the ball is indeed on the same level as that of their ProV1, but keep in mind that every reputable, established company at that level is going to press that button if they suspect that their research and development efforts are being stolen from any company, no matter how large or small, no matter how impressive or how insignificant their sales are. If it's your company and you devoted tens of millions of dollars into the R&D aspect - you don't want anyone stealing your concept.
Not to say that the Ksig ball isn't worth the $20/doz or whatever... I just don't think there's enough there to remotely put a dent in an established company like Titleist, so I don't think that's their motivation in pursuing legal action.
I think what they're doing is more out of principle than any real concern that this product is going to take a sizable chunk out of their revenue. And quite frankly who could blame them, when there are laws that protect a company from having their proprietary ideas stolen from them.
A year from now, the Ksig will be history and the only people who won't forget about them are those stuck with a surplus in their basement because they can't sell them on eBay for more than they paid for them.
