The Japanese release date for Tales of Hearts R has just been announced, along with the upcoming pre-order bonus and a limited edition version. The given release date is March 7, 2013 with a price of 6,480 Yen (roughly $87) for the game card pack or 5,830 Yen for the download version (around $78 ).
The main pre-order bonus given is a DLC code for something called Tales of Hearts R Infinite, which is apparently an infinitely progressive 2D action RPG of some sort. Still waiting on better details for this.
As for the limited edition of the game, called Tales of Hearts R Link Edition, will come with a Tales of Hearts R clock app, some accessories, and basically I believe more will be announced. The price is 9,980 Yen (around $133)
Tales of Hearts R will be released for the PlayStation Vita in Japan on March 7, 2013.
