Do they have any exclusives(system sellers) in the first half of the year?

Quantum Break, Halo 5, and Rise of the Tomb Raider are the only ones I can think about on the top of my head.  We also have the rumorred Crackdown but I doubt that'd be first half of the year.

I honestly can't think of any.

The way I see it. PS4 will crush xbox from Jan 2015 until Halo 2015. Then X1 might outsell it for that month and continue to get crushed every monthy there after.

2014 X1 had Titanfall with hype equal to destiny and Xbox people thought it would be the next gears. (if it was on PS4 it might have been). And that did nothing to stop the PS4. Imagine next year when they have Bloodbourne and the order Vs. nothing for xbox. The momentum from this xmas for Sony will just speed up. Halo is coming a year too late and to be honest with the MCC releasing (a top top game for any Halo fan) the boost Halo 5 gives it won't be huge.

Nothing like Halo 3 for the 360.

All of those are set for Fall 2015 or later.

Yes, it has.  Which makes it strange that they use the wording they do.  Steadily outpacing?  That would imply the One has won most months when comparing it to the 360.  No, the fact is the One had a great launch followed by a sharp decline.  Coupled with the fact that more people want the PS4, and therefore the One is dead outside the US and UK, it is easy to see that some time next year the 360 will pass the One and never look back.  Personally, I'm expecting ~40M, maybe 50M, lifetime for the One.

I also don't see how the One will make a comeback when it doesn't seem to have any exclusives to push it early to mid of next year, while the PS4 does.  Of course, better performing multiplats are a plus, as well.  And if there is a price cut, Sony will answer in kind.  And MS does not want to go against a $299-$349 PS4.  And as far as SO and MCC goes, those won't really push much HW.  All signs are pointing to SO selling poor to average.  And MCC is a remastered collection that will probably push some HW, but mostly sell to those who already have a XBO for Halo 5.

Finally, I don't see the point of constantly pointing to the PS3's turn around and saying that the XBO can do it, too.  Sorry, but no it can't.  Even with the blunders of last gen, Sony had much better sales in EU and Japan than the 360 did.  This helped balance out the 360's leads in the US and the UK.  The only thing MS can hope this for is maybe a turn around in the US and UK, something I don't think will happen after seeing the continuing sales gap in those regions, even after the many moves taken by MS to combat it.  Even if they could pull it off, the PS4 would remain on its heels in both regions, while still maintaining a commanding lead everywhere else.  The Xbox brand just isn't strong enough to stage that kind of comeback.  Not with inferior PR and HW prowess this gen.

Good point! XB1 has been selling WELL UNDER X360 after its debut. This article is one of the worst piece of wishful thinking text I have ever seen recently, completely devoid of genuine market analyses.

XB1, however, is released on an 80 million hungry user base (way over 25 million) and after 7 years (instead of 3). At the release of X360, the vast majority of people were still waiting for PS3. Only after the harcore initial buyers got their hands on X360 and people realised that they got a pretty even experience at a much lower price point, they started to jump off ship, especially with the advent of network effects.

Let me give you a bunch of statistics to depict you the vehemence of the situation:

XB1 vs PS4 sold in 2014 only (by 4 Oct 2014)

World:  2,913,121 vs 7,440,352 (28.1% vs 71.9%)
US : 1,665,728 vs 2,578,508 (39.2% vs 60.8%)
Europe : 701,833 vs 2,763,559 (20.3% vs 79.7%)

For comparison, despite all its disadvantages, X360 had still managed to sell more

X360 sold globally...

by the end of 2005 : 1,178,904
by 7 October 2006 : 4,839,500
X360: 3,660,596 vs XB1 : 2,913,121

Yes, PS4 is making XB1 look worse, but it ACTUALLY is worse! And its marketshare is decreasing even further.

Market shares for XB1 (between XB1 and PS4 only) in 2014

Global : dropped from 40.0% to 33.5%
US : dropped from 47.2% to 43.5%
Europe: dropped from 30.5% to 24.9%

Very little analysis of why PS3 made a comeback, and why those factors don't apply to Xb one. And for all that PS3 did make a comeback, which I think is an impressive feat, it still ended up selling just over half what PS2 sold. So if you apply that sort of comeback to xb one, you will get xb one lifetime somewhere in the mid 40 million range. Not a terrible result, but certainly a disappointing result and a real waste of what xb360 achieved. But the fact of the matter is on a launch aligned basis PS3 outpaced xb 360 right from the start, so a PS3 comeback was very predictable if you bothered to analyse the sales and not just look at the total sales as a snapshot. But because most people who don't use vgc have no clue about the sales trends and patterns they come off very ignorant when they try to comment on console sales. Vgc may not be accurate week to week but it is a very useful resource for analysing long term patterns and trends.

xb one should be ahead in the USA and UK. Most rational people had placed xb one in the win column for USA and UK even if most rational people had put PS4 in the win column globally. That xb one is highly unlikely to take the lead in those countries is the story of the generation. Ps4 was always going to be more dominant in Europe and globally than PS3 so what's happening there is not news. And xb one has no prospect of reducing the gap, all it can do is reduce the rate of increase, and hold marketshare.
Can it do well enough when considered in isolation? Probably yes. Is it going to realistically compete with Ps4 on a global scale? Probably no.

Actually X1 have sold well on launch and have been outpaced by X360 from the beggining of 2014, but I won't rain on this guy parade.

I think the author is being to optimistic. Halo is what will give Xbone a boost. If Halo doesn't do it then nothing else will.

The thing is, PS3 was bellow X360 in USA from the start and even if improved the situation still got outsold by a big margin (UK like the same)... but everywhere else PS3 were always ahead when aligning so it wasn't a turnaround it was "normal growth" just on a very slower pace than previous PS and with botched USA sales.
