It's been over four years since any Shining Force title graced a Nintendo system (not counting the Virtual Console), since which the series has been mostly limited to remakes for Japanese mobile phones.
So thank the heavens for Sega, which just announced a totally new entry, titled Shining Force Feather, in the pages of Famitsu. An all-2D strategy RPG, the game is due out in Japan next spring, and features a combination of isometric viewpoints (while out in the field) and a side-on view for battles (as seen in the scan snippet above). Best of all, it's in the talented hands of Flight Plan, who last developed Summon Night: Twin Age, which we really liked. Hit the "Source" link for the full, glorious scans and join us in squealing.
Update: Corrected factual error.
