@donnacha of WordSkill -

I presume that Germany, Denmark, Kenya, all of which are 2011 events, were already being organized by the time this rule was announced and would have had a good argument that it would mess up their existing sponsorship plans.

Your presumption is incorrect. We never said there could be no more "WordCamp [Country]" events. What was said was that once more than one person/group wanted to hold an event in that country, then it would need to broken down into city names so people would know which events were which. Some countries still only have one event/set of organizers, so they are still labeled that way. In countries where there are multiple organizing teams for multiple events/locations, it's not fair to give one team the bigger country designation and make their event seem like it is more important than newer organizer's events.

Of the 2012 events, precisely none have been allowed to use their country name.
That's not true at all. Most of the events in planning for 2012 are still in the "Planned WordCamps" column on the schedule page because they haven't nailed down dates/venue yet. If you had looked there before commenting, you'd see that Azerbaijan, Norway, and Croatia are all using their country name.
