Unfortunately, if you want an upgrade from anything that isn't WMR there's no point unless you're going for an Index, anything else is a sidegrade. Keeping your existing headset also means you have something to use when it inevitably breaks. 
I do plan on getting an Index later this summer, but if there was any other next-gen option that wasn't the Index, I would probably get that instead. I highly doubt there will be any large tech releases this year anyway because of chink aids.
