They will have to keep some form of differentiation, after all, why keep specific hardware in retail when a device exists that does everything better and all in one. Its not going to fly. Consoles are already extremely close to a PC in every way (for the same reasons, ironically), even the 'ease of use' part despite what some might think. The games are the same, the downloads and patch wait times are the same, or perhaps even worse on the console because its more rigid in every way. The only real difference is the amount of tweaks and settings you can change on PC, whereas console doesn't offer that. But even that is entirely optional; games can automatically be set to suitable GFX for each system. Basically if you start a PC today and click the download button, everything after that is done for you, you only click OK and Accept a few times along the way.
Beyond the technical part ALL of the differences, are in fact drawbacks for the console. The only reason the console could sell them as unique is because it also offers something that is unique that people DO want: the games, and most notably the exclusives, timed or not. Even something as silly as cheating, often used as an argument vs PC online gaming, is a very game specific idea and entirely a developer problem before a system's problem. As proven by the likes of Blizzard who can keep their PC ecosystem cheat and hack free, or 99% of it.
Console was never king, really. Its always been on the sidelines of PC progress and tries to step into the marketplace when there is profit to be had and the old version no longer gets exposure. The only consoles that were truly king, were the early Nintendo's, the Atari, the Commodore, who did offer things the PC was still not very capable of at the time... but beyond that...? The PC quickly picked up the pace and had its own share of games and its own market. Older consoles often did push some sort of special hardware to really one-up the PC in some way. PS2 had it, PS3 even had it by being backwards compatible with PS2. Nintendo consoles still have it; its the reason they've got their own little market segment and are not part of 'console wars'. But were they all round better, it really depends on what you're looking for I think. And that hasn't changed. Even today, the PC is still the optimal device for specific genres, for LAN, for massively online stuff, for anything that is NOT gaming but communal, etc etc.
Evidence of this can be found in global sales for each platform over time. The consoles barely, if ever, had a bigger reveneue stream than PC gaming as a whole. And even that is discounting the fact that PC has been the haven of free gaming since forever. Legal or not, free content is everywhere, if you really wanted to you could have gone without spending a single dime on content over the past two decades and NEVER get bored. That's a huge one that is often missed.
