True, but the newer consoles are getting bigger just like PCs, because a lot of them are pretty much smaller PCs. And I think in the future, they will have to get bigger because they are going to become more like PCs in the future.
I think we'll get one more console gen, and of course the new consoles will be massive. Because by this point you have to essentially make a PC. I think what will happen instead is that streaming by this point will become more sophisticated, where we won't need to have this massive hardware to play the game. We'll instead be able to stream a portion of it possibly. I figure streaming will not become the future, but, they could use a portion of streaming to put out the game, and the console for more resources. idk, just an idea.
