Not at this point they're not, the majority of exclusives are already announced. Games take at least a bit of time to market. Quantum Break, Halo 5 and Forza 6 are all 2nd half of 2015 games, there's nothing exclusive in the 1st half of this year for Xbox One.

As for Sony they have 16 exclusives announced for this year:

1)The Order 1886, 2)Bloodborne, 3)Tearaway Unfolded, 4)Until Dawn, 5)Fat Princess Advenvtures, 6)Ratchet & Clank, 7)Kill Strain, 8)Drawn to Death, 9)Deep Down and 10)Let it Die, those games are all AAA titles, Sony also has these indies: 11)WiLD, 12)Rime, 13)Everybody's Gone to the Rapture, 14)Shadow of the Beast, 15)The Tomorrow Children and 16)Alienation.

Nintendo has: 1)Mario Party 10, 2)Kirby & The Rainbox Curse, 3)Mario & Donkey Kong: Tipping Stars, 4)Splatoon, 5)Xenoblade Chronicles X, 6)Yoshi's Wolly World, 7)Mario Maker, 8)Devil's Third and 9)Starfox.

I may have missed some indie exclusives for Wii U, but both of these system have a considerably bigger library of games exclusive to them compared to Xbox One.

The argument that Microsoft could announce more games exclusive to Xbox One also applies to PS4 and Wii U, in fact it's downright guaranteed to happen in the next few months. What you should bare in mind is that Microsoft are the ones that are losing exclusives to PC, Sony and Nintendo aren't, they're actually vastly expanding their exclusive libraries for PS4 and Wii U this year.

I'll also point out that I said transition, which means it's a gradual process.

My stance isn't that Xbox One will be completely abandoned, it's that it will not be an exclusive box, but that's something that will happen with time, not by some arbitrary end of 2015 date.

Growth YOY? It lookes that way cuz last year the x1 was the but of all jokes andd the sales of jan and feb 2014 ws not very good to beging with, it got totally demolished by the ps4. The x1 will most likely see a decrease in the coming months, starting with march npd. This holliday they will be up, but the rest of the year will be horrendus.

Not the same as last gen. First the wii did not take awway sales of the 360 or ps3, cuz people had it as a secondry console, this time the ps4 is definetly taking away sales from the x1. There where some diferences in the conoles last gen, this time they will share 95% of the games, but the x1 will play them at a lower resolution and the few exclusives we get this gen, the ps4 will have more(Better will be objective). might be a battle in the US, but rest of the world the battle is over and there is very litttle the x1 can grow.

Second, Looking at how the market share is 61% US(acording to vgc), By the end of the year it will be at least 70% US. We know the holliday sales will focus on the US and like last year the disparity will be even bigger. For the 360 it ended at 57% US. The ps4 will take at least half of the US market share the 360 had and that half will be like 75-80% of the total x1's. 

So 48.32 50% = 24.16m In the US.

24.16 75-80% = 30.2 -32.21m global

That is the max I think they will ever sell, taking into account that all those RROD did not go into the 360's total, wich we know is not true, so Im gessing the x1 will sell is 20-25m lt. Maybe good for nintendo, but MS will see this an an insult and will abandon hip before it gets to taht while bleeding money. They wil never compete with steam, but its less money bleading by competing with them then selling hardware at a loss competing with sony.
