Ps4 (Including or Excluding VR). switch or Xbox? 

For me it looks like PS4 has it regardless of VR but with Psvr it looks like the most content packed year since the height of PS2. Please post your list to prove your point as I don't have a switch nor an Xbox and I still haven't looked into PS4's full 2018 line up.

My psvr arrives early this week yet I think I may buy a switch if the Jan sales turn up a good deal or I can find a used unit. 

Well, for the Switch it depends on whether or not the games are actually coming in 2018. If Bayonetta 3, Metroid Prime 4, Pokemon, Shin Megami Tensei V and Fire Emblem all come I'd choose that, but none of those have concrete release periods.

From what we know Sony > MS > Nintendo

If Lost Soul Aside comes out next year, then PS4.

Games that interest me that are expected to release in 2018:

Kingdom Hearts III (PS4/XBO)
Monster Hunter: World (PS4/XBO)
Yakuza 6 (PS4)
Dragon Quest XI (PS4/NSW)
Spiderman (PS4)
Shadow of Colossus (PS4)
Dragonball FighterZ (PS4/XBO)

I've probably forgotten a few, but so far it's PS4 for me.

~Edit~
Valkyria Chronicles 4 (PS4/XBO/NSW)
Persona 5: Dancing Stars Night (PS4)

Why would you say MS over Nintendo? I can't find much games to look for on Xbox at all. 

PS4. I'm not going to separate it from VR, even though I don't own VR.
Although I am excited for enough PS4 games without even considering VR.

PS4.

God of War? Ni no Kuni? Shadow of the colosus? 

Oh yeah, Shadow of Colossus for sure. Gonna edit that in and other games that come to mind over time.
Not sure about Ni No Kuni 2 yet.
