That's about all we have. A website went live a few hours ago, with the only clues being a city on a cloudy day and a quote from John F. Kennedy. Writers at Kotaku speculate that it is one of two existing S-E trademarks: either Front Mission Evolved or Vanguard Storm. We know nothing concrete about the game other than the info on that teaser site, but those two theories seem to be solid guesses.
Also, tomorrow at 2 PM ol' lasz will have taken his last exam as a college undergraduate. History of Rock and Roll. Woo.
