For me it's the upcoming Oculus Quest. I've been refreshing /r/oculusquest daily, hoping to get a release date or a way to reserve it.
Would be great to have one device that can operate as both a standalone device and be connected to a computer for more graphically intense experiences than the Quest's snapdragon hardware can provide.
IIRC it's running at a lower framerate than a Rift does, but it'd still be cool to have that option because I have no plans to buy a dedicated PC-connected headset.
Odds of this actually happening are probably not good, but fingers crossed anyway.
I got a gaming laptop right as the first VR headsets were coming out, and I'm just at the cusp of being able to power them with my setup, but the input ports may be my limiting factor.
Save those helmets. 30 years from now they'll be worth a fortune on fleaBay the way Philco televisions are now.
PSVR is unironically the hope for VR right now, even though it has by far the lowest quality.
It has some very good games (Astrobot, Wipeout, RE7, Ace Combat 7, Moss, Beat Saber). It's cheap, easy to set up (aimed towards couch VR instead of room scale), cool helmet design, and the fact that the headset works as a regular monitor for non-vr games and one person can be watching TV while the other person gaming, is genius.
Compared to let's say Oculus where you need, 4 usb ports (3x usb 3.0), cables everywhere, space, a ~$1200 pc/headset combo...
I do believe in VR though and am excited for what the future holds.
