How about I post what games Japan gets every month to see what we might get in future? This month's games are:
Super Famicom:
Clock Tower (August 3rd)
Nintendo 64:
Mario Tennis
Neo Geo:
Miracle Adventure (August 3rd)
With just 3 games for Japan it is easy to see why NA/EU isn't getting many games lately. Mario Tennis has been out for over a month too. Why did it take so long for Nintendo to release it there?
