Thanks for that link that directly addresses my Baron question.
As for the Duke weight, earlyups lists Marker's claimed weight, I've encountered another write-up that indicates that the actual weight of the new EPF will be 2790g, which is about 1/2 lb more than the current version.
Given how the Marker reps I've seen giving interviews from the trade shows have been deliberately even when pressed about the weight of the EPF, and how the new Salomon is actually lowering the bar weight wise by coming in a full pound over the current Duke design, I'd be willing to wager that the production version people will be buying in the fall will be closer to that 2800g mark than the current 2500-2600g range of the 2012 Duke.
I really like the low stack height & the external access to walk mode on the new Guardian, not to mention that it looks pretty darn sweet, but I'm going to take a pass on the 1st gen version of the binding and watch to see how it holds up.
Truth is, I don't need the burliest metal binding on the market. I only weigh 160lbs, ski DIN 9.0 for most conditions, have been well served by Marker Griffons for the last 3 seasons, and am thus inclined to go with Marker's proven Baron design, which will save me 3/4 to 1-1/4 lbs over the EPF & Guardian weights while touring.
On a related note: is it just me, or does the new Tyrolia Adrenaline design look to have the most ridiculously-exposed walk-mode release ever?

If I can casually flip up that lever with the flick of a pole basket, what's to keep it from opening if I cross my tails in the air?
