The GPL gives the licensor the choice (section 14. Revised Versions of this License.[1]): “If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.” As you can see, the default is to fall back to allowing any version of the GPL to apply. Many people choose to use the suggested copying permission statement, which includes “either version N of the License, or (at your option) any later version”[2], but some choose to only allow a specific version of the licence (the Linux kernel, for example). So, yes, the ODbL should take a leaf out of the GPL’s book, and allow the licensor to make the choice. OSM can then choose the option that suits it, which could well be “version N or later”.
