It should solve itself as others have pointed out.
FYI These were printed about 2 months ago in the mid west (where tonight it is 49F and 69% humidity) then spent a few weeks in Dallas (where tonight it is 61F and 78% humidity) and the possibly another week or so in another west coast distributor and on various trucks and DCs so they seen some fairly diverse climates. Paper is a such a porous substrate that it reacts pretty quickly to humidity so it can get this waviness pretty quickly
Here's a thought: how about putting a disclaimer to this effect on the WotC site? People might not be aware of this problem, especially when shipping books cross-country. Letting the consumers know that this is somewhat normal and usually will correct itself should keep too many people from feeling they got burned on buying these books or something.
