Breh, this is so overly dramatic that it's crazy.
This idea that that gaming market is completely unshakable is crazy, because companies fukking up and blowing their market position is a basic part of business. And even if it was a "black swan" type event for that to happen, you could argue that it's happened incredibly often:
Nintendo miscalculates cartridges vs CD-Roms, Sega completely mishandles the Saturn, Playstation is the unlikely winner of the generation.
Sony clearly dominates the next generation, but again, only by being the most stable option. Dreamcast dies early. GameCube does well, but is the weird console where Nintendo seemed to not be sure who their audience was. Xbox is new, but starts to establish its footing.
Sony gets arrogant, botches pricing and games for the PS3 launch, XBox 360 launches earlier and has a better launch window. Microsoft establishes a huge lead that Sony spends and entire generation chipping away at. Both are ultimately outsold by the Wii, so it doesn't really matter.
Nintendo completely and utterly botches the Wii U, and increasingly isolates themselves from a third party standpoint. Microsoft looks at what Sony did with the PS3, says "Yeah. I like that.
" and basically does the same shyt. Sony's investment in studios in the early days of the PS3 cycle pays off, PS4 wins almost by default.
This generation, Nintendo has accepted that being a niche/exclusive platform works perfectly for them, and have been INCREDIBLY successful. Microsoft has the money and infrastructure to not just compete with Sony, but actually won, if we're being honest. Only problem is that they need games.
This idea that Microsoft cannot compete with Sony and never truly has is preposterous. They're just doing what any smart company would do, and using their most abundant resource to compete: money.
It's only natural for their direct competitors to not just sit back and let them acquire that large of an asset.
