Thunder Blade has been announced for Japan.

To recap this year's releases that Japan has received so far that should hopefully be making their way West this Fall, Japan has gotten Fantasy Zone, Fantasy Zone II (Based on M2's modern arcade adaptation of the old Master System game that they created for the PS2 Fantasy Zone compilation), Outrun, Afterburner II, and now this.
Wave 1 last year saw 8 releases, so hopefully three more surprises like Turbo Outrun await us this season. And hopefully they continue the trend in being arcade based. Last year's 5 Genesis games were hard to get excited about in my opinion.

And similarly to Galaxy Force II from wave 1, gamer's that just remember the Genesis conversion are in for a treat since the arcade original is a very good game.
When Sega is finished someday, I really, really, hope they toss all of this onto a cartridge and release it at retail.
