What are people talking about? A comeback? Yeah,maybe in UK and US,but in continental Europe and Asia they never really took of. What MS needs to focus on,is Europe and Asia if they want to succeed next gen,because they already managed to establish a well known brandname in US and UK.

MS just need to keep doing what they are doing make sure they never launch a console like they did the Xbox One.

Evidently, Sony is hardly doing anything at all to achieve their sales. MS could have been doing just as well or dented the PS4's significant lead if it wasn't for the Pre-launch controversies.

I think everyone just conveniently forgot the PS1 and PS2. By Sony's standards the PS3 was a failure when compared to their previous consoles. And it sold over 80M consoles. Sony has always been the market leader since the PS1 gen. 

As for the OP, there is nothing they can do. Not this gen and not next gen unless Sony find a way to fuck things up which I think is near impossible when considering the path their on now. MS is at least much better off than Nintendo. They are still selling better than the 360 did and that's all they have to keep doing. If they cab get to 40M even if the PS4 is at 100M that would be a success in my book and would at least mean they are profitable and can't be ignored by third parties. So all they have to do is just ride out this gen and remain competitive. 

As for Nintendo.... they need to be very clear with what direction they are trying to go. cause its a bad thing when everyone is confused as to where your platform is going. I however feel the best thing they can do is make as close to conventional a console as they can and wait for the PS5/XB2 launch and be sure to launch along side them. And people always say Nintendo exclusives, but history has shown that a console cannot thrive on exclusives alone. Nintendo needs to take this time and secure third party partnerships. Cause an NX with Nintendo exclusives will be great, but will be greater if it also had third party support. 

MS got too specialized in shooters for me to want the console. When the 360 was the console to own it had games like Blue Dragon, Lost Odyssey, Mass Effect, Tales of Vesperia and Eternal Sonata. They need to diversify into genres I want in order for me to take the console seriously.

After hearing Kojima Production as second party to SONY, lol i doubt it will be easy for PS fans looking out for another consoles, maybe a gamer that have not decide will be the new target for Microsoft and Nintendo.

But Wii U doesn't have any chance and NX will competing with PS5 in the future obviously (it will not directly competing with PS4 ). But Xbox they always has their Ace card (money ) they always can buy every studio out there with a risk (loosing money )

But if Microsoft want they can just integrated AR Hollo lens to Xbox One, but i am doubt that will happen, because it will be to expensive for their fans to buy (more expensive then VR). But anything can happen, because Sony can just f**ed them self, but still SONY has learn a lot from the past.

Need to be worry though is another competitor outside mainstream gaming market which are Apple, and Google.

It's either "Sony was dead" or "the PS3 beat the tar out of the X360". I really wish people realize that just because your console isn't selling like bread doesn't means it's unsuccesful...

It sold good, came in later and so can last a little bit longer, so why criticize it?

As for current gen, I always had the impression that if Microsoft just said "screw this" and made an easy port tool to distribute their games through Xbox Live, it'd sell a lot...

I suggest Valhalla, Mistwalker, Platinum and Capcom... Especially Capcom... Alternatively, buy Bethesda and murder everything in sight...

Or they might make it easier by enabling all Windows 10 features on the XONE so that all they'd need to do is to ask devs to distribute their games through XBL as well. Everyone wins and nobody loses...

The gaming division makes most of its money from XBL. Consoles have always sold at a loss. It's subscription revenue that they profit from...

I know what they can do, Skyrim and Oblivion BC please.

A comeback, as in sales? MS could burn up a huge chunk of their cash reserves and buy Take Two, but, that's as unlikely as an Xbox One comeback.

Nintendo? Uh, free Wii U with proof of purchase of ten Amiibos?

The game was already set about one year ago.
Sony won by establishng the best format (in terms of price and specs) to play 3rd party games.
After this became clear to the market, it was only a matter of time for 3rd party support balance to shift on thier favour. Plus they have a stronger 1st party offering compared to MS.
All MS can do is damage control until thier next-gen platform (which will come earlier than we expect, since its not in thier best interest to loose all their marketshares against Sony).

What? Playstation brand never made a comeback, it was always big!
Imo Xbox One and Wii U can't beat PS4 anymore.
