Press releases are marketing talk, no question about that. Still, I find it easy to believe they have an R&D manager and hard to believe that they would lie about that new factory. Of course it's possible that the factory belongs to someone else, but if so, they're making these pickups to Epi's specifications. And it's not just the ProBucker. The Pro P90 and the Ceramic Plus were also introduced at the same time as part of the same line, and there are variations of the ProBucker. AFAIK you can't buy them elsewhere.
We'll just have to see about these when they get here. I can't make conclusions based on looks.
