My opinion is that it doesn't need clever nomenclature, so it could be an article called "Content on other regions" or "Patches in other regions" or "Patches (other regions)". It's a bit out of line with the typical page on this wiki, but it's pretty normal for other wikis. I proposed "foreign content" as the "clever" name, but I don't like it too much. I just came up with the (other regions) idea, but I think I like it. Regardless, it should focus on geographical naming rather than release state.
Edit: Actually, I guess using "Patches" implies a specific article structure like this one, so maybe it's not the best. Regardless, this is a minor detail and the name can always be changed later. Just pick a name for now.
