You have to factor in Magic Online redemption for the price setting of the Khans fetches though.

If there’s 2 expeditions per case, then the chances of getting any individual expedition in any given box is…

2 expeditions per case / 6 boxes per case / 25 expeditions = 1.33%

Likelihood of getting a particular FOIL Khans Fetch was ~1.7%.

Therefore, if the same amount of boxes are opened, there would be 1.33 expedition Polluteds for every 1.7 Khans Foil Polluteds = 78%.

Plus, BFZ will be opened more than Khans. So, it’s be *VERY* easy to see a world in which there are an EQUIVALENT amount of Expeditions Deltas, Floodeds, Windswepts, Woodeds, and Bloodstaineds as there are Khans Foil versions.

Therefore, I can’t possibly imagine that the Expedition Delta and Strand stay in the $200-$300 range when their equally rare Khans counterparts are $80-$90. They’ll certainly hold some kind of premium, but not 2-3x. I bet the Khans Foils drop to $70, and the BFZ Expeditions for Delta and Strand eventually stabilize around $100-$120. Tarn and Misty might be higher around $150-$175, but those will be much much much much more common than the Zendikar set foils.

Scalding Tarn, Misty Rainforest, Polluted Delta, and Flooded Strand may hold these obscene prices or at least close to them just by being blue. They may come down to $250 or so but the demand for these alone should keep them pretty high. The rest will fall but they are still going to be expensive for the most played ones.
