I'm gonna say it right now before someone thinks your serious. 

SARCASM!!!

Sure as hell won't be Nintendo

Sega didn't had the money to make the Dreamcast keep going the whole generation. Nintendo has. That's the difference, as they already did that with the Gamecube, nothing is there to stop them from doing the same with the Wii U.

I think they will all be able to survive but what do I know?

Is it only my impression or is most of the doom and gloom talk about gaming on Nintendo/Playstation/Xbox always coming from developers who make games for iPhone/iPad?

Non of them will go down imo. But we will see a decrease in sales during the next gen.

There's definitely some self-interest involved in these proclamations, yes.

First party games are what stopped GC from being a complete failure.

As it stands now, Nintendo made good profit despite the low hardware sales and a good number of the first party games sold well on the measly 21 mil userbase with games like SSBM, Mario Kart, M Sunshine, LOZ:WW and LM selling more than 3 million.

I have no doubt Wii U will do better than GC, so no worries for Nintendo as far as I'm concerned. They're probably the only one of the three who can sustain themselves without third parties

I don't think this guy is right though, Sony and MS would have to be dumb to not realise if the industry is on the edge or something. Iwata has already shown that Nintendo sees some of the problems facing us in the future.

eh.. I'd have to say it will happen but not in the same manner as SEGA.

Nintendo will continue due to its lower cost platform and highly successful IPs. WiiU will not perform 100m like Wii, but it will be financially successful before the year is out.

Sony will drop from the dedicated handheld market and instead push is phone/tablet playstation experience (digitally only) I think... but their home console strategy with the value driven PSN+ is a good sell. So long as their consoles are not super expensive like the PS3 was, they will continue to be long-term profitable far sooner than PS3 was.

MS will drop out of dedicated consoles all together and I think that will be apparent with the next Xbox. I've been saying this is the path for them all since early 2012, but I was only certain about MS as they were the only one with a full OS to begin with. Their next device will be a full media device that can also play games. It will be that end goal they always wanted with a real device running Windows connected to the TV as the central part of the family entertainment and other needs. This is the reason they entered the gaming market and this is the realization of that long-term goal.

This doesn't mean its gaming capabilities will be gimped, just that it isn't the sole or primary focus anymore. The mass consumer wants this device, but not in the uber gimped and hard to use SmartTVs/DVD/etc. Add the current 360 usage of all tablets/phones for control and a full / real smart/win8 device on your TV and that's a nearly perfect solution. My only wish is that Nintendo or Sony did similar but with Android as it would have been the most logical choice. After all, I'm certain Apple will do it this year along with Google in some sort of Nexus device.... but both won't have the first party content of the others.

Well, here's to 2013 and changing times... I hope your ready for change.

Well, I agree with part of this. Next gen will see a decrease in sales of HW, but not because the industry is in trouble. It will be because one console will be dominant, while the others will see decent sales. With the PS4 not having a gimped launch like the PS3 ($200 more than the 360 and 1-1 1/2 years late to the party), MS is going to have a large battle on its hands to prove the NeXbox worth the purchase to the people in Japan and the vast majority of EU. They may claim the US again, but I doubt the gap between it and the PS4 will be as much as the gap between the 360 and the PS3 is. The Wii U's fate is pretty much locked. Unless Nintendo does some crazy price cuts soon.

As for one leaving the HW biz, I doubt anyone will. Gaming is all Nintendo does and they have survived low selling consoles before. At the very maximum, I could see them dropping home consoles and sticking with handhelds. Sony's console business isn't in trouble, it's their TV department that's causing most of their problems. So Sony will stick in there, but may drop, or lower, TV production. MS is possibly the only one I could see leaving next gen. If the NeXbox doesn't sell as well as the 360, they may choose to cut the price to create a larger price gap between it and the PS4. This will be bad, as they will already be losing money on every sale, and this would lead to even greater loses. This may cause another outcry from investors to ditch the gaming market and focus on Windows. It just depends on if MS wishes to listen to them or stick it out til the next gen. I assume they will stick it out.
