Currently, Super Robot Taisen: Original Generation doesn't hit until 8/8, Deep Labyrinth doesn't hit until 8/15, and I can't even find a listing for Summoner Night. Don't worry, you'll see them on the list a week or so before they ship.
And as for notable Japanese games, maybe in the future, but for the time being, I'll leave that in the hands of our quite-capable JP crew.
