The sets that will be coming in 2018-2019 that have or have added HDMI 2.1 VRR capability will be bringing more to the table than just that capability. I understand waiting for a TV with HDMI 2.1 VRR support to avoid missing out on future capability, but I think once that is available in a TV there are likely to be numerous other reasons to buy that TV based on the improved capabilities it will have aside from that.
