Hmm I have no idea about Ghost, other than the fact that obviously it's launch should be far bigger than Mario because it's a new game not a couple of old ports, but the Galaxies will be interesting to watch numbers for.
Galaxy already being sold on Switch to the tune of 9 million copies with 3D All-Stars I think definitely hurts the sales of the Galaxies sold as a double pack. Though the fact that the Galaxies can of course be played on both Switch systems, and there isn't much to play on S2 yet, should help out the Galaxies some. I'd expect pretty decent sales of Galaxy 2 by itself since we've been waiting years as it was the odd one left out of 3D All-Stars.
l dunno, maybe the Galaxy bundle ends around 3D All-Stars sales lifetime a bit under 10 million, with a couple million for Galaxy by itself, and over 5 million for Galaxy 2 by itself. I don't expect these to have a big launch though launch week should be decent as people have been waiting for the missing Galaxy 2 for years, and should alright during the holidays but not like a major new game or anything, and should get a small boost when the Galaxy movie comes out, and probably as timeless classic Mario games they will continue selling with small legs for years to come, eventually getting up to those numbers I just listed.
