Honestly, I think modding consoles should be the next step for console gaming.
Consider the Xbox One and PS4;they're basically budget PCs that you can't upgrade but you're at least guaranteed to be able to play the games that release for the next however many years. But what if they were machines that like PCs could be upgraded with parts every year or so? Then we wouldn't have consoles locked to their strength at launch(which for Xbox One and PS4 is 2013). There'd be constant updates and upgrades and the consoles could improve right along with PCs if a consumer was committed to buying those upgrades;if not, they could get by with the base console.
Only problem I see with that is because its console gaming and not everyone would get upgrades, games would either-
A. Be made according to base specs, which defeats the entire point of upgrades in the first place
or
B. Be made accommodating newer specs, which would leave out those who didn't upgrade
If A, then people who upgrade are gonna complain. If B, then people who didn't upgrade are gonna complain. It'd be a hard sell to do this within the console market depending on how it'd work.
What would REALLY rock is if these updates/upgrades would be free, but lets be honest, thats dreaming. If it was free, consoles would have a real nice win in their column;budget PCs with free upgrades throughout the years of its lifespan that aren't comparable to top of the line PC upgrades but are at least good competition on a medium to high level.
Sony and MS are already giving out sales day by day, week by week, and month by month for games in their stores. Not quite Steam sale levels of price cuts, but they do what they do. In my mind they should keep pushing forward. Consoles are plenty successful in their current state but in an evolving world things need to change.
This in combination with support for in-game modding and oh damn. It'd be a solid evolution for console gaming. For now, both the PS4 and Xbox One are basically the same thing and will continue to be the same thing for the very long foreseeable future. But if MS and Sony want to bridge the gap between console gaming and PC gaming, this is at least in my mind the next step they should be thinking about.
