Mario will easily outsell it. More than easily. Splatoon 2 will sell less than Splatoon 1

i think splatoon 2 will outsell the original if they keep updating the game althroughout the switch lifetime and not releasing 3.... it will be more popular if they can execute a competitive scene on that game too... also if switch outsell wii u in a few folds it should be able to perform much better than the first game... i hope
