Well first, we definitely cannot count the Operation Rainfall games in your argument. Their future in America pre-Rainfall was questionable at best, especially with Monado coming off the release lists and not even getting a mention at E3.
Also, we were never talking handheld. Obviously, these games are all console so the discussion was limited specifically to that. Nintendo began handheld RPG publication on the GBA, and in many cases (like Pokemon) even earlier than that. To say that Nintendo "loves RPGs" is disingenuous at best. They ride a few series generation after generation.
Whatever deal they struck with Square Enix for Dragon Quest is separate and apart. They merely published VI and IX to take the risk off of Square after the failure of IV and V. Nintendo clearly was playing ball with Square Enix to secure that series for their systems (and clearly that worked, see DQ X).
I find it hard to believe that there was any intention on NoA's part to publish these games and had NoE not footed the localization bill, they wouldn't have come. If Nintendo was so pro-RPG, why is XSEED publishing The Last Story? Nintendo clearly sees these games as a risk and has adequately protected themselves from failure. Fan response to Rainfall made these games come to America, not Nintendo (of America)'s own impetus.
