Interesting, software is topped by PS4-titles, but Switch sells more hardware. Seems people are buying from a more diverse selection of titles on Switch.
More likely people who wanted a PS4 already bought it, so there's not that much room to grow. This is Sonyland, after all.
Plus, May is a time of a lot of first communions, so a lot of kids are going to get new consoles as presents. Just wait for the numbers at the end of the month.
You know it deserves the GOTY.
