As a primarily Nintendo owner, I personally will buy a PS4 or XBOne at some point, it's just that what is being offered at the moment is not really enticing. I buy Nintendo at launch because I know at some point there will be a Mario Kart, a smash Bros, one or two Zeldas, and some sweet sweet Mario, half of that list will be fulfilled by the end of the year. Add in surprises each gen like the Metroid Primes during the GC era or the 2d platforming revival+ operation rainfall games during the Wii era. But with the current PS4/XBOne library I ask: Where are the RPGs? Where are the massive open world games? These kinds of games made me want a 360 when the Wii just didn't offer those games, I bought a PS2 after playing Shadow of the Colossus and God of War I and II at a friends house. Bought a 360 with Red Dead Redemption, Mass Effect and Super Street Fighter IV. I feel that the only quality game that has come out on either the PS4 or XBOne that has interested me has been The Last of Us, but I'd rather buy a PS3 and explore that extensive library if that's the game that is going to sell me.
Let's look at your list:
Akiba's Trip: Undead and Undressed (PS4) (Nah.)
CoD AW (I'm done with FPS's this gen, I just can't do single player FPS's anymore, especially since most of my friends have not purchased either system, I can't commit to FPS multiplayer until more friends have made the jump to either the PS4 or XBOne. Call me a Luddite, but CoD has taught me that I do not enjoy online multiplayer gaming with strangers)
Assassins Creed Unity (this franchise has been hit <AC II, Rev, IV> or miss <AC I, brotherhood, III>, will wait for reviews)
The Crew (This has system seller potential, waiting for more news on this)
The Wolf Among Us (Will wait for steam sale)
Halo MCC (X1) (I like a collection like this, but it's not enough to sell me on a console yet, it's one of those games to get once you already have the console).
Lego Batman 3 (could buy this on the Wii U or 360, isn't a system seller, glad to see Lego games on system seller lists.)
Dragon Age Inquisition (Will wait for reviews, DA II was too repetitive and hype deflated with this franchise)
Far Cry 4 (This game looks really good. Sure it's an FPS, but there seems to be some interesting gameplay elements that make it look like a good sell).
GTA V (already played and finished on the 360, don't want any more ports)
Little Big Planet 3 (PS4) (I only played the PSP version which I was not too fond of)
Monopoly Family Fun Pack (Wii shovelware have become system sellers now? Seems like toward the end of this list the bottom of the barrel began to scrape)
WWE 2K15 (Nope.)
Two games (one has a vague release date) that in interested in, and two that I will wait for reviews since the quality of the franchises have been inconsistent.
But yeah, these lists like yours become opinions because unless you got set dates on Mass Effect 4, Fallout 4 or the next Elder Scrolls, I'd say there's only one or two games on the PS4/XBOne list you have there that look interesting so far. I'm sure those games will be coming at some point, but until then I'll wait, you never know if there will be a price drop on consoles by the time those games are officially announced and released.
Heck everything I said is an opinion of the game list you put up. If a Halo Collection is what makes you buy an XBOne, more power to you, gaming should be fun and not a Console Warz argument. If you are buying a PS4 for Monopoly Family Fun Pack heck, own that shit and have fun with it!
