for japan July 6th, I don't think there are any big releases whatsoever, however, a league could be done with
Metal Gear Solid 4 (PS3)
Super Robot Taisen A Portable (PSP)
Mario Super Sluggers (Wii)
Monster Hunter Freedom 2nd G (PSP)
Wii Fit (Wii)
Tales of Symphonia: Dawn of the New World (Wii)
Derby Stallion DS (DS)
Mario Kart Wii (Wii)
Powerful Pro Baseball Portable 3 (PSP)
Wii Sports (Wii)
I know it lacks new games, but I haven't really been paying atention to releases because I can't actually create a list. Also, it is Wii/DS heavy, because they compose the vast majority of the top 50 games for the last week.
