Hmm... well, given that neither the PS3 nor the Wii are exactly swimming in JRPGs, but the fair number that both have (out and coming) does make them a good complement to each other. Yes, take a look at Soriku's link, and determine if there are enough that interest you. I'm not sure how old you are, but if you missed some of the classics of the older systems, that just helps to push it even further toward being a good decision. I'd start with things like Secret of Mana or Phantasy Star 4 in that vein.
To those saying DS, yes, that is also a good choice, but I would recommend that to an RPG fan who has no other system. The sheer number of RPGs on the DS makes it expensive to have with another system; I know this all too well. (Not to mention that there's some junk to weed out.)
