Its not surprising. The Switch is successful and a lot of indie games are being brought to the system. There's a bit of a catch up effect happening right now where all the good indie games released on other platforms over the past few years are rapidly being ported to Switch. Eventually the pace of indie games will slow down to just new ones being created. However, I would fully expect the pace of AAA third party games to increase as they take a lot longer to port to the system.
