I assume they skipped 13 for the obvious reason. The only point of jumping to 15 would be to obscure that they skipped 13.
Not sure about that. I just recieved notification that Opera 12.16 was available for download. I don't see the changelogs on the Opera site yet, but they are apparently still developing the older version as well. I wonder how long that will last...till version 13?
