The prices on Amazon are generally cheaper than MSRP, so I would imagine the current list price would continue through the release date.
But keep in mind, even at the current price, it would be $68 for both, not including shipping.
Both of these items are also listed on yesasia.com, but at a higher price. Standard shipping would appear to be about $12 combined from what I can gather (it lists "ship units" as 4 for the Yotsuba, 5 for the Danbo, with a standard shipping rate of $1 per unit plus a base rate of $2.99 per shipment, and I'm assuming if you ordered both together, that would count as a single shipment).
HobbyLink Japan lists both items as cheaper than on Amazon (only 2380 yen each, or about $30), but there's no shipping information available for pre-release orders.
