No new ones are scheduled that aren't already represented in that list (that I know of). The Brown ones are still being shipped and the Green ones have yet to hit stores, but I want to say that Bento is sold out of the Blue and Cutlery Shoppe is sold out of the Orange.
There's also suppose to be a fluted carbon fiber sprint with either S90V or S110V, although as far as I know it's in the very distant future. They had one at the Spyderco prototype booth, the fluting looked cool, but the handles were too thick still so they were still working out the bugs with the handles textures, and hadn't decided on a steel for sure, but those two were the top two choices as of a month or two ago.
Sure, the more the merrier. Great ideas there. I've suggested a CPM154 Para2 before along with others.
I passed up on the orange, I remember seeing it on his site for $130 and not getting it. I'd like to get one and "half it" with a black/dlc now. Hell no I ain't paying $300 for one like I am seeing nowadays. So you see, I do have an agenda And at those prices there is clear demand for it. Why not, unless you have one of those that will get de-valued with a second run. Not my problem, I'm in it for the knives.
