Helloooooooooo!
It's already available -- you just need to use the Zoom Out feature in the upper left corner of the screen. Try it again - many of your compatriots are already there! Google just defaults to the US view (actually, to Kansas but I zoomed it out). I can make it a world view, but on other boards that I've set this up for, I got too many questions about how to zoom IN, so I figured it's easier to just deal with the few non-North Americans who haven't discovered the Zoom feature.
Good luck!
