It's not gonna happen, for the reasons Skunk stated. Jerry has plainly stated several times here and elsewhere that he's not going to do that, and he's never changed his mind on it. When I first read his statements regarding this (around the time he introduced the Ergo handles and discontinued the straights), I was disappointed, but now I'm glad he has that policy, and that he sticks to his guns on it. I have a lot of money (more than some, not as much as others) invested in older discontinued models, and reintroducing them into the current line would flood the market with them and adversely affect the values of my knives significantly.
Relax. It's still the same INFI. A few years and a few dozen Busses later and you'll feel the same way. It's all good.
