I got full body tracking when I got my Index in July. I enjoy it very much and it makes everything vrchat so much better.
I would say buy it now, since you don't knoe how long you need to wait for something new.
And If a better solution is released by Occulus I would probably buy that instead. But I'm not poor and don't consider VR that expensive.
If you have the money and spend more then 10 hours a week in VRC, go for it.
Other games supporting it is just a bonus.
