Also note:

Nintendo Network Premium also applies to DLC. Nintendo Network Premium will last until the end of December 2014. Points can be exchanged until the end of March 2015. NNP works with all publishers' content. 10% back in point form on every purchase (ex. 5700 yen x 10% = 570 points). As a criteria 500 points = 500 yen. Can only exchange points in 500 point increments.

Looks like Namco, TecmoKoei and Ubisoft believe it's better to give a price advantage to the consumer, while Nintendo. EA and Acti want to keep everything for themselves.
To be fair, i guess in Nintendo's case it's because they don't want to hurt their relationships with the big retailers.
