Funny about the quiet release, maybe they hoped most would not notice you could get them going in the back door. I imagine tomorrow there will be a section added, some notification and the rest it is here all while we've been playing for a day already.

Japan is a day ahead of America.

Lightning-fast on the WiFi here at work. Took about 5 seconds per game with the exception of the Ambassador Certificate and it only took about 15-20 seconds. In fact, it took longer to continuously navigate back to the download area after each game completed than it did to actually download the game.

It was pretty much the same thing for me. And if you don't want to risk it, you could always just wait a few days until the server strain cools down to download them if you haven't already.
