It's not plateaued, both manufacturers are simply trying to establish a solid platform for content to be targeted at. Think of it like game consoles; the idea is to make content easier and more profitable to create, in order to provide more value for consumers, creating a virtuous cycle. Fragmenting the market further by announcing marginally better hardware is not helpful for that goal.
Both HTC & Oculus have already shipped improvements to their existing hardware and I expect that to continue until the next generation of hardware is announced. Specifically:
- HTC has upgraded the tether, audio & head strap, revamped the packaging twice, are about to release trackers, are likely gearing up to release upgraded hand controllers and also new laser tracking hardware.
- Oculus have shipped their hand controllers, plus now support room-scale configurations with multiple cameras.
The list of software improvements on both platforms is much longer, so I won't bother but real-use performance continues to improve with the same hardware.
