I think this is smart, I don't understand why they don't do this more often.
A digital release costs next to nothing, retail I can understand you don't want to get stuck with unsold cartridge inventory.
They could do the same thing with games like Dragon Quest VII in the West -- I'd buy that for $25.
Even if you only sell 50,000 downloads between US and Europe at $15 profit/download that's still $750k in profit ... why not.
