This is fairly outdated, it was certainly true in 2013 but these days xbox is pretty much dead, playstation is stable but flat for a long time, PC has overtaken both, and mobile has shot to the moon.

The Steam Machine is a very niche product, but PC gaming is the main gaming platform outside of phone games.

> This has spooked Sony into pulling its new titles from Steam - they don't want people buying an Xbox to play Spider-Man games

That's not what happened, Sony's decision is more about the poor saels of its single player titles on Steam, they are now focusing their PC releases for online multiplayer games instead

Microsoft sells less consoles each month than the previous gen Nintendo Switch sells today

A lot of publishers are skipping Xbox, citing not enough players/sales

They have nothing to worry about Xbox
