My brother got REVII, but other than that I've made a vow to not buy games week 1, and to wait until there's a discount before getting a game.

Already got:

Halo Wars 2 (well kind of - offered to review for a site I write for and was given a review copy)
Legend of Zelda: Breath of the Wild (Switch)
Fast RMX (Switch)

Future releases for the rest of 2017: 

Sea of Thieves (XB One) (was a huge fan of Rare's games back in the day so I really want to give them one last chance, and I think this could be the game to put them back on the map)
South Park: The Fractured But Whole (XB One)
Binding of Isaac (Switch)
Has Been Heroes (Switch)
Mario Kart 8 Deluxe (Switch)
Skyrim (Switch)
Splatoon 2 (Switch)
Mario Odyssey (Switch) 
Xenoblade 2 (Switch)

So far I haven't bought any games week 1 this year, and I doubt I will. Breath of the Wild would have been week 1 if it didn't release on a new console.

Nier Automata Limited Edition - I preoreder this Friday, shall be home next week Thursday-Wednesday
Persona 5, maybe RDR2
I will buy Horizon and Nioh later, simply not enough cash right now.

Thimbleweed Park (already kickstarted/pre-ordered, out in three weeks!)
Zelda (Switch, already bought)
Nier Automata (PC, already pre-ordered)
Super Mario Odyssey
Lego City Undercover (Switch) => I'm not kidding
Ni no Kuni 2 (PC, provided it will be ported this year)
Mario Kart Deluxe
Xenoblade 2 (provided it will be released this year)
Yooka-Laylee (Switch)
Stardew Valley (Switch)

I would buy RDR2 week one as well if I had a system for it.

Crash Bandicoot
Wipeout Omega Collection
Yooka-Laylee
Stardew Valley (physical launch)

My list of certain week 1 games:

My list of possible, although unlikely week 1 games:

• Crash Bandicoot: N. Sane Trilogy
• Red Dead Redemption 2

Most likely none, unless some game I want happens to come out around the time I'm getting games for christmas. I will eventually be getting Nioh, Nier:Automata, Horizon: Zero Dawn and Ni No Kuni 2 at the very least, but I'm in no rush to get them right now.

Day 1 purchase:
- RE7
- Horizon
- Zelda BotW
- Super Mario Odyssey

Week 1:
- GT Sport
- Star Trek Bridge Crew
- Farpoint

Maybe week 1 purchase:
- Ni No Kuni 2
- Detroit become human

I want to get back to VR after Zelda and Horizon and not sure I want to play any more open world games this year after finishing those two.

Include Wipeout HD + Fury and Wipeout 2048.

It's supposed to be coming Summer 2017.
