Will the XB1 sell better this holiday than holiday 2014?

It could, but I think it's got some things going against it that'll prevent it from doing so.
Aside from Halo 5, Forza Motosport 6, and Tomb Raider as their main exclusives and a solid exclusive lineup, I don't know if it can.

Last year it had Sunset Overdrive, Forza Horizon 2, Halo: Master Chief Collection, which was a solid lineup of exclusives. And they were backed up by a price cut, Assassin's Creed and Call of Duty bundles, whereas the PS4 didn't really have anything new to offer. And it all benefited in Microsoft's favor (for North America)

This year, it might get Assassin's Creed again, but now Call of Duty has moved over to the PS4, and Black Ops III will be the biggest title this holiday season as far as sales go, and Halo just doesn't have the same value and appeal that as it used to, and a big part of that is because Call of Duty has swooped in and claimed the throne, and now is not letting go.
I don't see any plans for another price cut looming. In fact if anything, I think there's a stronger chance that we will see both a PS4 AND a Wii U price cut before we see an Xbox One price cut.

So I'm gonna say, it won't sell more, and that it'll sell around the same.
