Personally, I don't think it's that strange it is not released in the US.
In europe football is a big thing (soccer for you yanks)
With the new PES relying heavily on the D-pad, they made a special controller for it.
Since nobody in the US gives two shits about soccer, it won't come out there.
Simple right?
Besides, the US usually gets all the good stuff, like the limited edition halo console and stuff, now we have a measly controller. Let us have our fun.

Just because the vast majority of US citizens have no love for soccor (not me; I played on a team as a child), don't assume that we also don't care about D-pads.
