RH, read what egordon99 said. Then read it again. Forget about the "And then Canikon would blow out the snow" part, that's unimportant. The point about dynamic range is the thing to take away. Then again, I'm sure you consider a 12 or 14 bit sensor capable of capturing 12 or 14 stops of dynamic range respectively..
Metering with Pentax is what it is. The photo posted was using pattern, so even using centre weighting as you suggest *would* have helped, as would spot on the bison and snow to get a feel for the full range. Bottom line, there are ways to deal with the metering, like dialing a few stops of +EV. It's just a matter of knowing the tool, and while it's a shame that the OP is frustrated with the exposure of the scene, it is a tough one to capture regardless because of the dynamic range. I don't care what brand you use, it will take a bit of work to get the desired result in a scene like this.
