After seeing NSMB2's Japan sales and how they are tracking significantly behind NSMB's Japan sales. I feel that this might explain NSMB2's potentially worrisome sales.

"Once upon a time, Super Mario Brothers 2 came out in Japan. The game is essentially a rom hack of Super Mario Brothers 1. Some new things were added like the whirlwinds. But it uses the same exact game engine and the same graphics and sound effects. "
" Aside from the fatal flaw of the lack of accessibility caused by the difficulty, Super Mario Brothers 2 Japanese was a flawed product because it was little more than re-using the same game engine. "
" Stagnant is the word to describe Super Mario Brothers 2 Japanese. The game adds new mechanics but nothing to the Mario universe. The engine is re-used and makes the game feel stale. This complaint about Super Mario Brothers 2 Japanese does apply to the new 2d Mario games. "
" I don’t think Nintendo understands why we buy 2d Mario. They probably just think it is about the ‘gameplay mechanics’. Let me ask Nintendo a question: if you guys were blind to the 2d Mario demand for decades, what makes you think you understand what is all going on behind the scenes today? "
Keep in minds that SMBJ2 sold 2.65 million units in Japan while SMB 1 sold 6.81 million units (According to VGC for both numbers).
