Serious Question concerning Oculus

I have my Vive and my family and I love it. It got me and my wife back into gaming after many years. We ordered an Oculus way back when but won't arrive until July. That's fine we have the vive to hold us over. However, I have some lingering doubts. I want to support VR in general. Not one company over an other. I think it's the future of entertainment. I do have some issues when I play steamvr games that support both Vive and Oculus. When I play a Vive only game, I feel great "presence" and I've not felt any nausea. When I play something like IncellVR or Time Machine VR demo, I get weird vertigo. I don't know if its just because I don't see my hands in VR in those games or something else but my worry is that all oculus games will make me feel this way.

Secondly, I worry with touch only coming as an accessory, that the market will be bifurcated and since most oculus buyers will not have touch, then most games too will not have touch.

What are your experiences with Oculus games? Nausea or no? Will touch be supported widely or just a select few games?

Thanks.
