i could see this happening-
on the day of release, nintendo releases a level pack containing the 3 NWC levels
a few months later Nintendo releases the entire orginal SMB game remade in SMM
as time goes on they do the same for SMB3 and SMW
about a year later they release an update adding a Challenge Mode. basically a few Nintendo made levels are up for a set amount of time and players compete for the fastest time. similar to the NWC
