I still think that they should release MGS: Peace Walker as a stand-alone game like they are doing in Japan. At least they should put the game on PSN in the future for someone that already has all the games and doesn't want to buy MGS2 and 3 for the second or third time.
Also, I'm the only one who would to see God Hand remastered for the PS3?
Time Travelers (not sure if this one in particular is an RPG)
from Wikipedia: Time Travelers is an upcoming video game "without a genre" for the Nintendo 3DS which is being developed by Level-5. Besides obviously involving "time travel", the game is said to contain a "massive, in-game world"."
