Standard SLI is horrible for VR, it adds quite a bit of latency because of the way it's designed. nVidia has a new type of SLI coming out, VR SLI, which solves this by having each card render one eye rather than each card render every other frame. But VR SLI needs to be specifically supported by the developer, and nVidia has been slow to get the SDK to VR developers.

Do some research on SLI on this forum. The topic has been beaten to death. It currently doesn't work at all, and it probably won't work for a while. In theory, it may be possible but would require very special programming (e.g. Nvidia VR SLI) and won't be an automatic thing that will just work in any game.

It's not up to Oculus to support SLI but to game developers (or, rather, engine developers). The issue is that traditional multi-GPU rendering (AFR) is horrible for VR and just won't work. So engine developers need to create custom rendering schemes and most don't bother for a small niche market. Even multi-GPU for 2D games is slowly fading away as more of the onus goes to developers with limited time and budgets. And, even in the best case, multi-GPU will add some amount of latency, so you could end up with a worse experience. Though it's not impossible, so maybe one day it will work.

Just want to rant about the No SLi or Crossfire support from the ground up. Why limit the technology to just the processing power of the one card instead of n cards? What was the logic behind the decision made at that point?
It just pisses me off when developers limits themselves like this. I wonder how much more would that have taken just to develop the SDK with SLi/Crossfire support from the beginning?
Anyhow, I would no doubt, move to a developer that support SLi/Crossfire first. Hopefully either HTC or OSVR are exploring these paths.
All I want is VR to be out of this single card cage!! We need better graphics for VR now..

it'll be encouraging to see if Oculus would change their stance on the SLI tech and push to optimize it further.

Why do you keep saying that? Are you being a troll?
