BTW, Nintendo does have a habit of holding certain releases back for a couple years until near the end of a system's lifespan.
For example, I'm guessing Xenoblade Chronicles, The Last Story, and Pandora's Tower (or at least the first two) were almost always planned to release in the USA so when every one else was freaking out ;-) (Operation Rainfall) I wasn't too concerned.
And now after a few years, we get NPC Pikmin 2 ^_^
My favorite example of this though (and it's an awesome RPG to boot) is Tales of Phantasia (GBA - the ONLY English version of the game :-);
it came out in the USA about 3 years after its Japanese release ;-) (2003-->2006) right at the end of the GBA's lifespan.
