This is not a very good comparison at all, since Nintendo has the advantage of starting reporting years later, when digital spend was overall higher, across all products and markets. So I couldn't be bothered to regraph, and you'll have to deal with a rough edit of the current chart.
Even with the above immense bias in their favor, Nintendo's digital sales lag behind after the first year, and show no real positive trend at all.
Keep in mind that all the Nintendo quarters are being compared to PS3 generation, not the current gen. Even without PS4's success, Sony's digital growth strongly outpaced Nintendo's.
