Sometime today, Street View fans should be able to take in sights on all seven continents for the first time ever.  Coverage of Brazil and Antarctica will make this possible, and images of Ireland are supposed to become available, to boot.

We can't guarantee the timing of this development, as a couple of details don't add up.  Problem one: the new Street View images aren't available at the moment.  Also, although Josh Halliday quoted an official Google blog post, said post doesn't seem to exist anymore.

Still, according to Halliday, the blog post stated, "We hope this new imagery will help people in Ireland, Brazil, and even the penguins of Antarctica to navigate nearby, as well as enable people around the world to learn more about these areas."

And the images should go live soon, considering that Google isn't yet facing any legal challenges in these regions.  Indeed, Ireland's Minister for Tourism, Culture, and Sport is excited about Street View, and Google just took pictures of wildlife in Antarctica.

A couple more facts: this update should cover almost 50,000 miles of Irish roads and at least Half Moon Island in the Antarctic.

UPDATE: Google came through, and all the new Street View images can now be found in Google Maps.
