Will sell way more than 4 Swords. So no it will not be the lowest selling console Zelda game.

I did say mainline home console game so it only includes LOZ, LOZ 2:AOL, ALTTP, OOT, MM, ww, TP & SS. 

How so? It's a Zelda game on the Gamecube.

It's not considered a mainline game just like how metroid pinball isn't a proper metroid game.

It is. It´s also in the timeline.
