I'm most excited for the BK17, it looks great, and the size is perfect.
Other than that, I can't say that I'm genuinely excited about any of them. Not that they are bad in any way, but I'm not waiting for them to come out like I am the BK17.
The Machax is likely the closest I am to being "excited" for, but that excitement level is actually below some other current production models (BK7 to be exact). I really like the 9 as my chopper, and I'm not sure yet that the machax will be a huge improvement for me. I'll of course eagerly await reviews and comparisons to prove myself wrong though

(Passaround?).
The Combat Kuhk looks pretty cool, but I'm not sure what I personally would do with it.
I not a huge fan of large folders, so while the ZK Mule folder looks sweet (can't deny it, I totally agree with you BRL), I don't know what I would use it for either. The little chinese folder doesn't look too bad though. And seeing how its MSRP is so low, it might be REALLY cheap, and I might end up picking one up, who knows.
Honestly, I'm most likely going to end up with the BK17, and either the BK7, or the JAB Potbelly in the coming months.
Oh, and are all of the US made Kabar blades going to get the new laser engraving and coating?
