To know that we would need to know the full software numbers of each console, and they haven't told us that in a while. I do buy most of my games retail, digital only seems like a pretty poor value proposition to me. What could be an interesting point of discussion is the factors of digital purchases on the Switch. On one hand, it's a handheld, so for portability's sake digital makes sense to allow playing all of your games, but on the other hand, the console has quite a reduced memory for that, so it makes sense to support physical format, at least for the bigger games.
