New Dungeons and Dragons license less sleazy than I believed?

After hinting that the new Dungeons and Dragons license would be aimed at phasing out the older open licenses, Wizards of the Coast have published more details suggesting that this won't be embodied in the license itself (though they haven't published the license or its terms of use yet):
Q. Do I have to give up my right to publish 3.5 OGL products in order to publish 4e compatible products?

A. No. Publishers are free to print product lines under either the OGL or 4E GSL. We would love to see our industry colleagues convert their entire product offerings to 4E, as we are doing, but we do not expect or require entire companies to convert to the new edition.
