No, I don't expect anything significantly better or cheaper than the pucks for the next year at least. 

In research, there are some projects to do body tracking from rgb cameras + ML, but they all require a bunch of GPU resources and nobody is trying to commercialize or even make an open source version of them. There are some pure magnetic/inertial trackers as well, but also only research or more expensive commercial mocap (perception neuron). the vive tracker technology is technically open and DIYable, but the only existing project https://hivetracker.github.io/ is pretty dead, or at least I've never seen anybody actually make one besides the paper writers.
