Bethesda being bought up has messed many people up. Seems like this is the first time they realized you can't have everything with just one console.
You Always Had To Decide what you could live without when you intentionally tie yourself up to one ecosystem.
There was a point in time in the console space that where you had games come out only on some hardware because it had capable CPU/GPU technology similar to PC hardware. (Doom3, HalfLife2) Sure ports happened to downscale on some game releases but those were for the "mainstream" type of games. (Splinter Cell, Prince of Persia etc) So you had more reason to have those expectations of missing out.
As Consoles got better hardware, PC developers started to finally be able to have some parity releases on the console space. Games typically found only for PC could now be enjoyed on your comfy couch playing on PS3 and Xbox 360.
As time went on, this kept improving. Now consoles could even support mods like its PC brethren but in limited fashion.
I guess my point is that for the longest time consoles have been making so much progress that so many doors opened up for all types of releases. (Hello VR).
With MS buying Bethesda or anyone of the 3 buying a publisher will now limit this progress that we've enjoyed for such a long time where all the consoles could enjoy all types of pc games. Its like we are going back to those times where only OG Xbox could run PC releases while the PS2 couldn't due to the hardware. Except now, its more than possible to run these PC like experiences at 4K but we won't see them due to ownership of said publishers being bought out. Guess the industry had a good run.
