Currently, we divide the events by year, then region once we reach 2009. Generation I and II events are currently split only by generation, but I have no intention to change this due to the fact that they worked differently and were very uncommon.
What I propose is that we split events by language and generation rather than region and year. This solves the issue created by splitting NA and PAL events when they have a Wi-Fi event that distributes to all English language games. Also, distributors need to actually distribute different events bewteen languages, but this is not necessary between regions with the same language. This would also mean that Greek and Dutch events end up on the English page though, as this is the language their games use.
It also means that we don't have a blurred line between Generation IV and V events on the 2011 (2010 for Japan) pages, and the same goes for Generation III and IV. It is the most logical way to divide things, it is how people would be looking for events, and it is how event distributors would actually need to create separate event Pokémon.
Also, I would like to propose that we put event items and Pokéwalker courses on these pages too. Anything with a Wonder Card deserves to be on these pages.
So instead of names like "List of North American Nintendo event Pokémon in 2011" and "List of PAL Nintendo event Pokémon in 2011", etc., we would have "List of English Nintendo event Pokémon in Generation V", "List of German Nintendo event Pokémon in Generation V", "List of French Nintendo event Pokémon in Generation V", "List of Spanish Nintendo event Pokémon in Generation V", "List of Italian Nintendo event Pokémon in Generation V", etc.
