I think it sold like 2 million copies. You got to remember just how badly the Wii u sold. I think it was less 15 million units? We're talking less than 10% of what the switch has sold. From that perspective, it was definitely a no-brainer to try and get every game they released on it ported over to the switch.

WiiU sold 13 million units.

I do wonder how they'll pace the release schedual for Switch2 though.  The argument for creating one hybrid system was so that all their development teams could focus on one system, thus providing sufficient new releases all through its lifespan.  That certainly worked, with a number of first party releases left for this year still.  But that roster of games was bolstered by Nintendo rereleasing nearly their full WiiU catalogue to an audience who never played those games.  They won't have that luxury this time around, and development will take longer and be more costly due to the higher fidelity.
