End Official Release 
Nintendo is touting Resort as a 'long-tail' title, meaning that it sells well over a long period of time and accrues an impressive sales total that way rather than having a blockbuster opening week and than fading quickly.  guess that's a pretty accurate dipiction of the whole 'blockbuster vs sleeper hit' thing. If you could really call Resort a 'sleeper hit', which I don't know if you can....
