Kingdom Under Fire and the associated series are the only major KRPG product out there that I know of, since Lineage is a PC-only game.
Phantagram has made enough cash and such to make the KUF series PC/Xbox/360 only since it's inception.
And in that case, the crappy spin-off, Nintey Nine Nights (made by Phantagram and another noname Korean studio) sold 50,000 units in Japan, nearly 200,000 in the US, and an unknown # in PAL territories. Which wasn't too bad considering the fact it's a spinoff, and only claim to fame was "it's made by Phantagram".
A little factoid: according to a recent Famitsu chart I saw, which incorporated sales data from themselves, gfk, and many other sources I've never seen before, Korea is the X360's 3rd largest userbase in Asia, and has sold over 125,000 units there as of 3 months ago. That's not alot by many standards, but considering the top-selling PS2 never even managed 2m units it's entire lifespan, it's actually good (for comparison, that'd be like the X360 selling 1.5m units as of June this year in Japan).
So with the 4th Kingdom Under Fire game coming out, and Phantagram staying souly in Microsoft hands (despite the fact they only use MS as the publisher), leads me to believe one of the few console-side Korean products is doing well.
Also, despite no knowledge, Magna Carta 2 (another KRPG) is still slated for a X360 release, despite #1 being a PS2-only game.
Back from the dead, I'm afraid.
