I was looking at this bike a few weeks ago at the LBS and it seems a hidden gem. Half way between fatbike and 29er. Run some slighlty smaller tires than the stock 29 x 3.0's and I'd never have to worry about mud clearance (an insurmountable problem where I live) again.
Also, after a few test rides I'm sold on the concept of fully rigid. Fun!! On a 29er! ;)
I love everything about the Krampus and ECR except for the Knard tires themselves, which don't quite deliver as much traction I had hoped for considering the massive contact patch. Here's hoping a 3rd-party tire manufacturer steps up to the plate with a nicer compound and casing!
