I'm not going to deny that VR is a very expensive hobby, but if you're really enjoying yourself, I think it's worth it. 
Also I think you overestimate how quickly new gear will come out. And even when it does, it might not necessarily be superior to the current options. It may be more affordable, but a bit worse overall.
Worst case scenario, you can sell your stuff on ebay for a small loss later on.
