It depends on what they consider their userbase. I do think that 20-30M console sales would remain even if they gone full 3rd party as long as GP is day one only for xbox.

What page is your reply on, and I'll read it again, if you haven't changed your opinion, since for some odd reason, you simply don't want to update your reply or at least repost it.

Anyway, Sony will want MS's 1st party games, did you forget MS own Bethesda and ABK? All MS have to do it make CoD exclusive to GP and all future Blizzard games. Thats MS's GP killer app. Otherwise, another company will take GP and Sony customers will miss out which will hurt sales. 

That would be great, because it would raise the bar for Sony. For too long Sony could bank on the consumer attitude of "at least they aren't Microsoft."

Conventional wisdom says that competition is good for the consumer, but what has it really brought for the consumer through the past two decades? Competition didn't stop online multiplayer from getting put behind a paywall, it didn't stop any of the AAA industry's money-making schemes, it didn't maintain the quality of games at launch as day one patches followed by multiple patches afterwards became regarded as a normal thing. And of course paid-for exclusivity of games is also a consequence of competition that didn't benefit consumers as a whole. It isn't too hard to name two bad things for every one good thing that happened because of competition and there is definitely no net gain for the consumer here.

Conventional wisdom says that monopolies are bad, but for one, Sony wouldn't have a monopoly anyway with Microsoft being gone; on one hand you have the PC with high-end graphics and on the other hand you have Nintendo who share a very high number of games with Sony below the AAA level (as does the PC). And two, is portable console gaming worse since Sony has exited and left it all to Nintendo? The opposite is the case.

Sad. I don't want to pay 700 USD in my next Playstation 

Good response. Too many are funneled into believing competition is the savior to this industry, when in fact, we have seen nothing but the complete opposite over the generations. A good example of this is that those people that want competition, are the first ones to whine when a game is exclusive and not coming to other platforms etc. Competition actually divides the consumers and the business model, it breeds fanboys and console wars and brand damaging etc. What is even more crazy, is that competition actually ends up costing the consumers more, because they need to purchase more platforms and services to play all the games.

PCs are living proof you don't need competition and ironically PCs offer the best value in gaming, no online paywalls, best and more common discounts, bigger variety of games and the list goes on. Meanwhile it was competition that brought in online paywalls, it was competition that raised game and console prices, it was competition that actually takes the consumers for a ride.

In saying all that, Xbox leaving wouldn't leave a monopoly, Nintendo, Mobile, PCs are valid options to gaming. 

I'm not happy about this. competition is good and gets us better prices for games and hardware. switch is like the perfect example of why the competition is good when it comes to pricing its 7 year old hardware that still hasn't been discounted and the games as well.

So you prefer Xbox to stay around so you can have cheaper Playstation consoles? You do realize that if Xbox stays around, they will fight for exclusives and instead of paying more for a PS6, you will lose out on games. I would rather pay more for a console that has all the games than pay less and miss out on half the games. 

We have competition now and prices have been going up. Sorry to say, competition isn't helping. 

 I don't understand responses I have seen from many people like this, expecting Sony to run rampant with horrific negative consequences for consumers. If Xbox left the console hardware business it would not give Sony free reign to do whatever they want and screw over consumers however they wish. Negative decisions that are harmful to their userbase will hurt Sony regardless of if Xbox consoles exist or not. Gaming is a massive industry and there will always be competition from other platforms and services whether that is from traditional console hardware or something else. Where there is opportunity someone will take it and providing a poor level of value to your customers greatly increases that opportunity for others.

There will always be competition in some form because there will always be companies looking for opportunities to make money.

Steam have basically a monopoly on PC gaming, but they haven't become horrifically anti-consumer. Why? Because they won't stay at their incredibly dominant position for long if they start screwing their consumers over.

you remember the ps3. when there is no competition sony can basically get away with everything. they can make everything worse and focus on profits because there is no competition.
