Japanese media briefing in April: new RPG?

So it looks like Microsoft of Japan will be dropping the skinny on some new games that'll be on the way for the Japanese (and maybe other countries too).
Takashi Sensui will be giving a 90 minute presentation to the media on upcoming titles for the Xbox 360. Remember that bit we did earlier this month regarding a mystery RPG? Famitsu broke the news concerning a yet-to-be-announced role playing game that reportedly has huge potential to sell big numbers over there.

This could be when we finally hear about that RPG title. The write-up mentions that the worldwide market will get a taste of this announcement too, not just the Japanese. Could this mystery RPG, whatever it is, make it to the States? Maybe so. The media address won't be until April 6th, so keep your ear to the ground for more on this later.
